Me too.
However, I heard over the weekend of a grocery store in Canada where you have to let a machine scan a QR code on your phone in order to be allowed in.
I suspected it all along: one will need a smart phone to buy or sell. Harmless... only preparing folks for the mark of the beast.
Online stores are only using smart phone scans for UPS/FedEx labels on return merchandise. I had a hard time contacting the company for a printable label.
