I can totally see this being abused by bouncers in this town.
I can't even count the number of times I've seen people tossed from bars/clubs when they weren't making trouble just because the bouncer didn't like them for any reason (or had some prejudice about the way they look/act).
So now if they don't like you or don't like the way you react to getting tossed for no reason they can ruin your night by getting you barred from everywhere else and getting you flagged as a troublemaker?
It's a good idea IN THEORY (as are so many things) but there's just way too many ways it could be abused in my opinion.
I have a really bad feeling about this.
PS: I'm not super paranoid about the privacy aspects of this, but there is some part of the back of my brain that thinks that storing data from your identification every time you go to an establishment is really wrong.
Bouncer licensing is coming this fall. Idiots won't be able to be doorpeople any more. They will have to go through the same type of training and licensing as security guards etc. No criminal records, first aid and safety training etc.
Look, this thing has been running in Vancouver for 5 years, no one is complaining about it there, except the gang members that have to go to Red Robin now, instead of a cool club.
