i'm looking forward to the day the cell phone kills the wallet. it's a matter of time. people will ask "you used to carry a plastic card with you that you swiped?" like we thought it was silly to carry around checkbooks and write cashiers a check.
- rjett 16y agoWhat hurdles need to be cleared before this can be done? I know that CCD and Camera based barcode readers can read a barcode off of a screen so how hard would it be to generate a unique barcode for each card in your wallet and just scan your cell phone if you wanted to make a purchase somewhere?
- gojomo 16y agoBarcode versions of existing CC numbers would be a simple and direct port... but think of the possibilities where your 'card' is now an internet-connected app (rather than just an account number). Perhaps your phone receives (by camera-scan/bluetooth/etc) the payment request, then the app approves/records the purchase.
