This isn't private medical information. Every single bouncer that I've encountered knows that I'm an organ donor.
That may sound rude, but what I mean is that these bouncers aren't saving and categorizing the information for monetization purposes.
And would you feel the same way if you found out that one of the bouncers has been scanning every drivers license and then selling the extracted data?
On the other hand, while the information on your drivers license is private, the information you choose to put on your public facebook profile inherently ceases to be private.
