Cash has been replaced by cards but in some countries like china cards are being replaced with qr codes scanned in via a mobile. This is where bitcoin payments are going to be done in future

exactly, the celphone itself becomes the card,

Actually for now bitcoin payment can do with qr code, because some wallet online have featured to read address via qr codes. If it can be used by a lot of merchant, i think card is not used again

That's right, enough with the QR code on the cellphone.
For what are the cards created, if there are more sophisticated tools?
