This sounds horrible. You could basica= lly monitor anyone with a wallet in a highly populated area and track them s= uper easily by doing facial recognition. Yes you could photograph people but= it's way more burdensome. Sorry to go off topic a little.

I hate to break it to you, but you broadcast a photo of= your face every time you walk outside ;)

Bluetooth= MAC addresses are random, they aren't useful identifiers. If someone can se= e you, a face is a far more uniquely identifying thing than a MAC.

"Payment spam" might be a problem. I can imagine a wallet re= quiring that such requests are signed and then spammers can be blacklisted i= n the usual fashion so they can't push things to your phone anymore. Anyway,= a hurdle that can be jumped if/when it becomes an issue.
