Could square be used on my own device to pay bills?
Enter my payment recipient company (or select from a drop down list of companies one has a prior business relationship with).
Enter account number for payment (could be a typed in number, a barcode or a QR code).
Swipe my own credit card to apply payment.
Bill paid, records kept, stamps not used.
FN: Could also envisions something like scanning a QR code for each payment, loading a few in, then swiping ones credit card just once to pay multiple bills faster.
