  1. What I would really like to see is this digital receipt idea taken further. If my card number could be securely tied to an account somewhere, open id style and opt-in of course, then the swipe could produce a digital receipt in a standardized format. This receipt could then be automatically sent to Mint, my email, my accountant, the accounting dept. if it’s a company card, or wherever the owner of the card chooses.

    This would be awesome for keeping track of my purchases on something like Mint. Right now, Mint guesses at what I bought, based on the seller ID, but it’s often inaccurate since some retailers sell a wide variety of things (e.g. convenience stores). Also, I often will buy the same product at different stores, but they are classified differently by Mint. If it had the actual receipts from each transaction, Mint could show me spending history on a per-product level without guessing.

    1. Closer inspection of their site (i.e. actually reading it) reveals that they appear to do the whole e-receipt thing pretty well; several other nifty security features as well (picture ID!). All that’s left is a standardized format and adoption.

      1. It’s nice to see Mr.Dorsey innovating something new again.. Surprisingly it’s far more different than his “twitter” inspired work.

        Squareup is something that should have been done years ago, finally its on the way for a skyrocketing release.

        The only caveats here is will its availability only be hindered by iPhone only? Hopefully that’s not the case. And the bullproof security users are clamoring for?

      2. The best part about adoption is that it does not need network effect. A seller can use this solution without the buyer needing to change of her habits/tools.

    2. I agree… the implications of this are going to be interesting to say the least. I am looking forward to the changes and how it will force the incumbents to adapt/change. It is fun to see a young company cause upheavals.

      1. What’s interesting is that this sort of system isn’t in place already, established by the existing companies. This looks like it will become a classic example of how disruption has to come from a small, outside company. Large companies really need to learn how to take advantage of the startup model.

    3. This magnetic dongle is kludge that is doomed to fail.

      The nexgen of cc will have RFID — and apple already has patents an enhanced version of RFID for it’s nexgen iPhone/itouch (and other handset vendors are certain to try & catchup to apple) … In fact it is just as plausible to imagine that the cc function could also be embeded in the customers’ handsets themselves (eg japan) – which would make RFID smartphone an end-to-end solution for both the merchant & his customer.

      If this guy had bothered to think through his business model, then he would’ve realized that an OEM model (with an accessory vendir) would have given him a more flexible position in the value-chain: currently he is directly exposed to large-scale changes in the payment environment.

      Alternatively he could have simply acquired an accessory maker (cases, batteries, stands, etc) as a platform (with brand equity) for a series of emeded solutions.

      As it is, he has a one-trick pony that is going to be rapidly obsoleted by RFID developments.

      …and this is how people get 10mil in the valley.

      Jeesh! I have got a dozen ideas that are better than his, so where do I sign up for the “idiot” money?

      I guess that vc’s have a rule that says if u have one hit under your belt then u r entitled to fail upwards thereafter!?

      1. Even if everything you’ve mentioned is true, it’s still a great device for me (freelance designer) to score clients I would not have been able to do in a cash-only transaction.

        The square its self was free, and took two days to get to my house once I signed up.

  2. I guess people to people commerce is the sweet spot. Mobility & ubiquity (assuming acceptance from growing number of mobile devices) is where it’ll trump PayPal. Not directly competing with major credit card companies is a big plus.

  3. Don’t know why they would spend resources working on a hardware attachment. Why not try to come up with a totally software app solution that allows easy financial transactions with any smart phone? That is where the world will be sooner rather than later.

    1. Given that it took them a month to develop it and the little it costs them right now, it makes easy. It is also a full magnetic card reader: they need to do that in order to accept credit cards etc.

      1. Why not just hand your credit card to an iPhone merchant and let them type the numbers into a web page? The faux security that comes from dedicated hardware will be completely lost when the hardware is in the hands of any random hacker.

        How will you know that they aren’t copying your credit card for latter use, or just selling the card info? Because of the special hardware/software from square?

      2. I myself would not trust my credit card with any random Square reader. I wish credit card companies would come up with a card that generates temporary number with credit limits, like I can do at many credit company web sites – maybe something like the hardware security tokens.

        Another idea, and maybe it already exists, is an app (e.g., iPhone app) from my bank that can generate a temporary credit card number that I can “beam” to the vendor’s iPhone app – no need for a hardware swipe.

  4. I would be particularly interested in how Square could provide a simple and seamless solution that enables a way to do expense reporting automatically through mobile credit card transactions. If your mobile could capture all of your business trip transactions and either, in realtime or batch mode, dump them into a corporate expense system, that would be a huge time saver for the employee and a huge cost savings to the employer.

  5. That photo is kinda weird lookin. On my iPhone, the headphone jack is on the top right end of the phone, not the bottom left.

    1. Well that is not actually a phone in the photo above, it is an iTouch, and the jack is on the bottom right of it. But regardless I think it is an awesome device and it is essentially an all-in-one Point Of Sale system, and the most convenient and user friendly one at that. I would love to use this device and was actually waiting for someone to come out with one as soon as I saw those credit card terminal apps popping up in the iTunes App store. I think its a great idea and I’m also impressed they decided to make an attachment using the audio jack, pretty cool stuff. I’ll definitely have my eye on this venture.

    2. Well that is not actually an iphone in the photo above, it is an iTouch, and the jack is on the bottom right of it, the iPhone’s is at the top left. But regardless I think it is an awesome device and it is essentially an all-in-one Point Of Sale system, and the most convenient and user friendly one at that.

  6. I think this is a great concept and I’d sign-up but the reader looks rather flimsy and I’d be concerned that it will break off leaving a prong in my audio jack. Will it stand up to heavy use ?

      1. You would be astonished what kind of damage and punishment a customer can subject ordinary items to. Ever notice how the keypads on ATMs are practically armor-plated? That’s why.

        So this dongle needs to be strong enough to withstand a forceful card swipe, dropping, torque, shear forces, and a myriad of other stresses that it might incur while plugged into an iPhone.

        The good news is that, Colin, a simple pair of tweezers could remove a stuck plug, if those are your fears. Chances are also good that there would be wires attached to a damaged plug, which you could pull.

        The better news is that the image they are using in this blog is clearly a prototype – commercial versions would obviously be stronger and probably contain several measures against wear and tear.

    1. @Gabriel ATMs are meant for public usage. It’s vulnerable to abuse by people since ‘noone’ owns it in particular. You don’t pay for the damages if you were to thump your fists on the ATM screen. However, if you mistreat the dongle or the phone, you sure do have to buy a new one yourself.

      Also, it fits in pretty much the same way as a regular headphone jacket. So the risks are pretty much the same as those for the headphone.

      Therefore, again, what heavy use?

      1. An ATM was probably a bad example. Perhaps the keypads found at gas stations and convenience stores, for you to enter your PIN number? They are similarly protected with a thick layer of rubber and a nearly bulletproof screen. I have watched customers take the stylus from those pinpad displays and literally stab the screen with the stylus clutched in a fist – if you believe that customers will be even marginally gentle with things, you are wrong indeed. This is less because of the ‘heavy use’ and more because of the ‘constant use’ aspect. If the chance of someone accidentally smacking their purse or hand against the Square (generating dangerous amounts of torque, judging by the prototype up there) is even 1/10.000, then it will probably happen within a business’ first week open.

        If you get a chance, take a look at the stoves that restaurants use. They look like they could withstand a small bomb, and they are like that because of the constant use and abuse that the business requires of them. This is a general rule that can be applied to most if not all industrial grade items, they are built to crazy high durability standards.

        Another explanation would be that a pinpad breaking or malfunctioning would disrupt a checkout line, and some businesses may only have one – they depend on this POS for their sales, and without it they might as well be closed. Business owners demand high performance out of their electronics, and we can expect the same out of a production model for the Square.

        From an engineer’s point of view, the design is beautifully simple – which leaves plenty of room for insulation, reinforcement, and padding. From a design point of view, this will be plugged into highly mobile iPhones and laptops – therefore it will probably stay small and portable. I predict it will become tapered and sleek, both to prevent accidental breakage and to make it appear more ‘one’ with its partner electronics.

    1. Think of the mag stripe as transitional: it’s hard to get many people to think a new thought, so you feed them an old thought in a convenient package until you have them hooked!

      adoption + (something like Bump) – mag stripes = World Domination!


  7. I see the tremendous value is in its way to bridge customers’ in-store experiences with their online experiences.

    This is a great innovation that will send the dinosaur POS to its end and free up, enlighten today’s retailers who are so hands-tied to the stone-aged POS that prevents them competing with their online peers.

    For example, BestBuy knows everything you buy and predicts well what you will buy because when you check out, you told them all your personal details.

    But today’s POS can’t capture the valuable customer information and that puts brick-n-mortar retailers at an disadvantage to engage and stay in touch with their clients any time.

    A LOT of innovation will happen for sure if today’s retail stores are freed from the antique POS systems. For example:

    And retailers have a better way to reward loyal customers.

    I can go on and on, this will drive a lot of innovation.

    Way to go, guys!

  8. This strikes me as a very clever way to address an immediate need, but it also seems to me that the physical card is a relic. We really should just carry the equivalent in our iPhones as an account number, pin and the appropriate crypto keys to protect them.

      1. Yeah, I’m guessing the mag strip is just to get things going. They’re on a fast track out of use here in Sweden, as chips are becoming mandatory in stores.

  9. I think phone device manufacturers are its competitors – iPhone or Android could easily do what Square can do. this is just a card reader. We had similar idea of having a card reader attached to a computer keyboard. It is only matter of time why Apple would not offer a simple card reader option to iPhone buyers so that they take CC.

    Once you swipe the CC, all you need is a Gateway, like PayPal, to process the card.

    the receipt analysis seems the only unique thing in this. Rest seems to be a good idea, packaged well.

  10. As the son of a business owner, I can tell you that the struggle to accept credit cards is a painful, expensive process. The readers cost money, and then you need to pay the companies outlandish fees per swipe – they get away with all this, of course, because strong companies have enough profit to make the payments, and those who don’t… well they won’t stay in business long enough to complain.

    Linking this idea, as Alec noted, to more information such as open ID and purchase information transmitted in the swipe would be wonderful!

    Just like what Google Voice did for phones, this will do for credit cards – it’s amusing see how the big companies will scramble!

  11. While this is very cool, what happens when someone walks up to me in the street with a knife/gun and an iPod, and makes me pay him $10000? Surely the system can’t be 100% traceable and trackable — there must be ways around identifying the recipient somehow?

  12. I don’t get why you need hardware and/or a card reader?
    Just type in the number into an app?

    Ultimately we need to move toward a UID and PIN for all transactions. Europe is way ahead of the U.S. in this factor– not only with financial transactions– but also stored personal medical information.

    I think there a couple of tough issues right now:

    1.) Developing a standardized UID (an “owner” of these) will be a tough nut to crack– I think eventually email addresses will go away– maybe just your mobile number will become your universal ID.

    2.) Payment systems are a mess. Everyone wants to charge for access these pipes from the credit companies, wireless carriers, to the banks. We need to open this system up and make transactions as easy as handing over paper and coins.

  13. What’s the average churn rate for POS? I seem to remember shops only refit every 7 years or so on average? But within that timescale I can see this having a huge impact for sellers. Obviously the consumer adoption for the likes of Craigslist will be massively beneficial to driving this change with traditional retailers.

    Once Smartphones become cheapers and 3G broadbrand is bedded down in developing markets – across Africa for example – I can also see Square becoming gamechanger with a positive social impact.

    Will be wathing with interest.

  14. While I agree on the potential of a person to person payment system, I cant see why it cannot be done with a simple app where you key in the credit card number. Why the swipe device?

    1. 16 digits – do you have your favorite credit card’s 16 digits memorized? And can you input them on an iPhone (successfully) in under 3 seconds? Probably 99.9% of the public does not – could not.

      I still think the security risks of this outweigh the benefits at this time. I would also like to see someone come up with an OpenID-type solution so that I am not giving someone my CC information which they will store on a very personal and very portable device.

    2. You can just enter a credit card and charge with this app (3.25% given to square)

      If you swipe the card using the reader, they’ll take 2.50% instead.

  15. As a customer how do I know the iPhone is not jail broken and runs a little app which records my data?
    I for one do not want to hand my credit card to anyone. If I buy something over the net or phone I use a temp credit card number which just has enough money on it to pay for the transaction. I would do it in a restaurant if I could.
    As a customer I want an iPhone app which creates an temp number with enough money to complete the transaction which I can “send” to the other apps for completion.
    This looks more like a sellers solution, with no improvements for the buyer.

    1. “I would do it in a restaurant if I could.”

      But you don’t/can’t, so there’s really no difference here. Besides, you’re already covered by the credit card company for fraud or malicious use.

      1. Why should I be stuck with today’s business model?
        Besides I’m lazy. I try to avoid problems before they might occur. Last time I checked the credit card company would not reimburse me for my time.

  16. What about adhering PCI-DSS requirements/standards? In other words, as a consumer how would I know the card will not be skimmed? In addition how will it be able to read the EMV chips which are mandatory in the European region?

    Square, it’s a great idea, but many hurtles to overcome.

    1. This is not a “card-present” transaction. no different from typing in your credit card number on a computer screen. So no security requirements. The corresponding merchant discounts will be high owing to the risk profile.

      Overall, i see no benefit to the dongle except to soothe consumers.

  17. I’ve had a small business for 20+ years. I’d be nervous as a cat with a merchant that whipped out his cell phone to process my credit card transaction. Color me old-fashioned, but I think this opens the door to serious security issues.

    And on another note, is cash really becoming that archaic? Is that whole “payment for all debts, public and private” now just an antiquated notion?


    1. So you’d be nervous to give out your credit card (which you already give to waiters all the time) that’s backed with fraud protection by the credit card companies, but would gladly pay with handfuls of cash that come with no protection from being mugged whatsoever?

      Cash is considerably more insecure. If someone steals my credit card, I cancel it and fraudulent charges are refunded. Cash is gone for good…

  18. Strangely, neither the article nor the comments mention a couple other clever bits.

    The reason to have a physical magnetic stripe reader is that card issuers and processors give merchants a far better rate when the physical card is present than if a card number is typed in. With this system, there is apparently no way to enter a card (I may be wrong), or it may be required to flag manual entries separately, to be charged differently

    These guys could have written an image-processing library that would do OCR of a card’s numbers, too, and all smartphones could have handled that. Less hardware. But I assume the reason they didn’t is that it’s better still to do a physical swipe. With the card in hand, and a physical swipe, the merchant can enter the three-digit security code on the back, too.

    In one of the illustrations on Square’s site, a signature is shown on a receipt. So I wonder if the app also allows someone to do a “touch” based signature. If so, that provides an even better rate: card present plus signature = the lowest fees. (Even better would be that the merchant snaps a picture of a buyer which would be stored at Square until the time for a chargeback on a transaction had passed.)

  19. Thanks @om for this good in-depth article about Square and exploring this venture, the idea. Much better than the +4 from TC.

    I agree that this one has potential some might not see (my comment from yesterday http://www.techcrunch.com/2009/12/01/square-receipt/#comment-3130655 ). Sure, it builds on top of a technology platform and can be accused to be a feature. But that doesn’t stop people to innovate and make existing processes more convenient, tear down the one or two walls, and lower the barriers of entry to a price of an iPhone/iPodTouch.

    It has lots of markets and applications, research reports always focus on B2C, but I have yet to see numbers in the P2P market (flee market, street stand (hot dog anybody?), selling T-Shirts/merchandise for onetime events).

    Square will have its success.

    PS: This again proves, that innovation and entrepreneurship is nothing about leap frogging (that is R&D). It is about constant improvement, iteration, changing the concept and approach, and misusing existing stuff.

  20. I attended a training by professional trainer Roger Konopasek recently. I guess what he said is true. We live in an age of disruption. If you fail to change and adapt, someone else will eat your lunch.

    I believe square has the potential to change the way people do business, especially Consumer-to-Consumer. People can just make purchases from each other as consumers or small business owners. However, the smartest thing to do for the developers of Square is to find a partner (like Apple).

  21. What dissappoints me about this – the backend is still going through the oligopoly of Visa/MC. When I hear “p2p” and “payment” in the same sentence, my hope is for something as simple and costless as handing over cash. We’re starting to see that in Africa where mobile carriers are building their own transaction-processing backends. But can’t there be some more open way for processing these payments?

  22. In Europa credit cards are all with chip, and if you use magnetic card you have no payment guarantee. When will Square be with a chip reader ?

  23. Has it occurred to anyone that an unscrupulous person could “accidently” bring up a sound recorder app and record the audio from the dongle, then sell it on the internet or play it into another device that has the Square app installed.

    This square app encrypts the data. It should take about 12 hours for some bright hacker to either hack into the Square software or build an app from scratch that will convert the audio file to a text file that contains all the information from the mag strip.

    Of course they will need the dongle. Wait I have a MP3 to cassette adaptor in my car that has a read head and an audio plug… I wonder…

  25. Well, the credit card form factor has remained the same or has changed slightly since its evolution. In the context of today’s e-/m-commerce the same[cards] may not hold true and hence SQUARE instead of trying to build a peripheral around cards should have designed a new “One Interface” physical or electronic.

  26. I read in a forum about iswipe which is similar to square have been around for years before square was revealed to the market. But when I went to the iswipe website there is a difference. I swipe needs a merchant account and a monthly fee which will cost you more unlike square which is free.

  27. The disruptive nature of mobile technology is at its very beginnings. This is the power of a marketplace such as the Apple App Store. All people see at the beginning is the “neatness” and shiny luster. Sure, games are fun for a while, but are they really the long term goal for mobile touchscreen technology? This “shiny factor” is exactly why an iPhone app is on average accessed only 19.9 times over its life cycle, according to Greystripe.

    After the exterior coat of sparkly newness peels off, application utility becomes more obvious and more of our daily chores and processes move to our mobile devices. Imagine a handheld touch screen device on which you can download absolutely any piece of software to help you with your specific daily routine. Ah!

    This is the reason we got into the business ourselves. Gone are the days that a restaurant has to buy a $3,000 paging system with 50 paddle pagers and manage their waitlist on a sheet of paper on a busy night. Now it’s possible to manage your waitlist and page your waiting customers from the palm of your hand.

    Jack, very excited that you guys are developing Square and are helping singe the trail to the obvious outcome: your life will soon revolve around your mobile device.

  28. Iphone App?? that is a main priority? Where is the windows mobile App?? Since windows mobile users outnumber iphone users by 10 fold. Business people use windows mobile based phones and regular consumers use iphones, so I don’t get what they are doing?

  30. What excited me most about Square is the possibility for reps and “superfans” to sell e-tickets using this software on behalf of events promoters and artists. Integrated with an online promotion platform this means that everything would be electronic. A promoter would list the event and tickets on their website then invite their reps to sell. These reps could then use person-to-person sales alongside their usual Facebook links and other online referrals. When they sell in person the receipt will be sent directly to their phone via SMS, shortly followed by their e-ticket, which contains a barcode. The guests can then turn up and flood into the venue by having their phone screens scanned. This is the final piece of the jigsaw for seamless promotion, sales and operation of events we’ve been striving for. And what’s more, no trees were felled for paper during this process so we can save the world one night out at a time! But we do need a chip and pin version first for the UK and Europe.

    Here’s the future. Ready?

    You have your encrypted financial info on your smartphone. Your touchscreen is a thumb print verifier so that only you can access your financial data.

    Through Bluetooth, you beam your transaction approval data (account, amount, encrypted thumb print “signature”) to the other smartphone.

    The receiving smartphone then Wi-Fi’s or 3Gs up the data to the clearing house for payment.

    Thank you.

  32. The dongle is not PCI compliant because the audio signal can be recorded by software in the phone, storing all the credit card numbers. Also, I feel sorry for the company that decided to take all the risk associated with having non-merchants giving the ability to take credit cards. Epic fail if you ask me. Paypal tried doing this before and it failed because everyone was using it to pay for back alley transactions…
