People will know their past with the swipe of a card.
Oh, and I personally value my privacy over my safety. These kind of proceedures are being introduced because western society is trying to handle all the crime that plagues it in the club/pub scene.
Ask yourself why violence is escalating at these establishments.. Fact remains, these places sell alcohol, alcohol intensifies ones current mood.. If everyone is fighting more and becomming agressive, what does that tell you about peoples general collective state of contentment and happiness? That they're not content or happy!
By doing something like this, we are becomming more exposed to everyone else, we are becomming more the pawns, like cattle, we will wait to be admitted and checked to make sure we are ok, and not a threat - In the same way meat is checked for contamination. Where's the dignity in that? Instead of presenting measures to tackle WHY there is an increase in violent behaviour and a more common hostile mindset, the governments seek to root out those who are not compliant with the system, and turn them away. This is a treatment, not a cure.
Only the strong survive? Correct
Only the obedient prosper? This is something that is becomming more apparent.
I may have elaborated into seemingly off-topic issues, but they are all interlinked with the matter presented - as it goes deeper than mere electronic card swiping.
