I’ve recently learned about Square: the latest startup of the Twitter-famed entrepreneur Jack Dorsey, and what he promises to be a revolutionary system for electronic payment.
The premise is simple: a wireless, cell-network based credit card reader - so simple it’s been done before, dozens of times; Apple already does this in their retail outlets, using modified iPhones and scanners to complete customer purchases from anywhere with WiFi, but Square is different, it revolutionises the payment processing of plastic by bringing the technology to everyone through a small plastic reader.
Square itself is a small attachment to any device with a 3.5mm audio input, that’s your iPhone, iPod touch, Zune HD, Windows Mobile, Android or even a laptop. The Square software then decrypts the audio back to a number and sets up the transaction. A quick signature from the payee on a touchscreen interface and you’re away. Square is s hosted service too, so the moment a transaction is completed a receipt is available online and confirmation sent by email or SMS. This transaction recording also allows companies to be informed when a repeat customer buys their tenth coffee: no more paper loyalty cards to be punched.
It’s simple to see now how Square is a technology full of potential: from coffeehouses to craftsmen to craigslisters, Square allows credit card transactions with existing hardware, no payment gateways, anywhere with a 3G signal. So when will Square reach you? “We’re trying to get the cost down significantly and just give them away”, says Dorsey in an interview of CNBC, “We’re aiming [a rollout] for March”. Dorsey wants to see one of these plastic squares in the pocket of every American. Some have criticised the operation, saying that Dorsey has developed technology with no use: with Japan already moving to a cashless economy using mobile phones as payment devices - but a cashless society is fragile with frightening Orwellian allusions, people like to be able to access their money in physical form, it makes them feel safe.
But there are of course downsides: Square is going to face the same if not higher levels of fraud as other gateways and will have to put up contingency funding; in it’s current state, Square cannot be used in the UK and other countries with the EMV standard for credit-security as it just scans the magnetic strip which doesn’t hold the encrypted PIN - it is effectively extending the use of a fundamentally insecure system. Square have also, so far, only invested in the iPhone, and although they promise to roll this out to as many devices as possible, it makes you wonder if the service will always be biased towards Apple’s mobile devices. While still in beta, with twenty locations currently trialing the device across the startup-heavy San Francisco, it will be interesting to see this product evolve and if what seems to be a brilliant idea can become a lifechanging reality.
