Does literally anyone scan an RFID chip from a business card?
I just... don't believe that is a thing that happens. Seems like a way to look "high-tech" that an actually high-tech person would never bother with.
Business cards are for reading a name, title, business name, phone number, email address, and MAYBE a business URL. What the heck are we even doing here.
Whatever business use is being achieved with these paper RFID tags... if it isn't for some kind of security gate to prevent shrinkage, a barcode would work just as well and is dead reliable.
Unless I knew for sure that I could trust the person who handed me the card, there's no way in hell I'm scanning an RFID or a QR code or anything else on a business card. It sounds like something someone would hand out at DefCON and then announce later in the day that they've used the card to compromise any device that scanned it.
