Square users are now able to email cash instantly to a recipient via their debit cards. Called simply "Cash", all you have to do is register your debit card details on with the app, which works on iOS and Android devices, and then, when you want to send someone some money, you send them an email, cc–ing firstname.lastname@example.org in on the mail. Simples! (Just ask users of Google Wallet, who have had this system in place for a few months now.)
But can both firms convince Americans that this method of sending cash works? The system is already fairly prevalent in Europe, with all sorts of firms offering up a cash–via–Internet service there.
The mobile payment firm claims that the system is 100% secure, although didn't respond to The Verge when it asked Square about its anti–spoofing methods––that's when you're duped via a forged address, a technique used successfully by some spammers, who send out emails purporting to be from PayPal, eBay and even delivery firms such as UPS and DHL.
