Exactly. I work at a place in the centre of a large city in the UK. Security is hot on badges. I especially know this as I smoke, so going downstairs every couple of hours needed a signing in/out session. To be fair it reduced my habit quite a bit. Now i've got a proper badge - I can flash anything I like, including my drivers license, or my debit card. The mere act of coyly moving something on a lanyard to them is sufficient, especially now i've explained that i've got noise cancelling headphones so I sometimes cannot hear. The best bit? There are government departments in the building on a floor below us. Even better - I used to work at a company that used to be part of the security services in the UK but were spun-out. They still work with the doughnut down the road. In heightened security times they do random checks of cars - mirrors underneath, etc. All I had to do was say "you checked me yesterday" and they'd not bother. Social norms trump process every time.
