Transfers instantly from my account to another person or business, all it takes is a phone number or QR code. And I can also send request for payment.
Only drawback is there is no protection like with debit/credit cards, so no chargeback.
I see that as an upside though. Fraud (and other protection) is essentially an insurance service you pay for, often in several percent premium. This service would lose its utility to me if I had to pay a premium to cover fraud. We already have debit/credit for those who want fraud protection.
I'd love to be able to hand folks a simple string or image, and have them able to send funds to me instantly, irrevocably, with no fees, and in a way that they can't pull funds back from my account (cough checks / ach).
