RFID is silly to put in a card that 99% will forget about and leave behind. QR codes are better as they are just the same ink that goes on it anyways.
Yeah I think that was the original point the other person was making but it sounded like you were arguing against that. I think we’re all in agreement, a QR code is a cheaper and quicker method of doing the paper>electronic data connection than whatever the tech in this article is describing, unless they can increase storage a massive amount.
