I don't understand why anyone is treating the display of a QR code as an advertising concept that an agency invented.<p>1. This is what QR codes are for<p>2. There's a whole section in QR codes ensuring this is possible<p>3. This is not even close to the first solely QR code advertisement<p>Don't get me wrong - it's douchey for CoinBase to pretend they came up with something<p>But also ... did ... did anyone come up with something here?<p>It seems to me like it's pretty similar to my saying "you should fill that glass with water," then you filling the glass and saying it was your idea, then my saing "how dare you, I invented filling with water"<p>I don't get it
