Re: Stamps go digital - Collectable Blockchain postage stamp
That being said, is it possible to know the color of the stamps bought before delivery? I'm asking because i noticed flo123
is now able to trade Green and Black stamps. How is it possible to know at this stage?
Well, you just have to scan the QR code on the front side of the card, then it'll tell ya which color it is... pretty cool stuff overall ... I really like it!
What do you use to scan it? Just any QR reader app? Or just hold the phone up to it and the phone scans it automatically? (mine typically auto-scans QR codes). Or is there a certain app youre using?
