I worked in all ranges from "you are fired on spot for letting you display on" to "no badges at all".
It depends a lot on corporation size.
There'a a time where we are supposed to use a barcoded card to gain access to company sectors/floors.
I forgot that card at home desks, restaurants tables, offices too many times...
Since a worked a lot with barcodes I managed do reproduce my own card barcode and let a spare papper copy at my wallet.
Short history: when management realized I can reproduce anyone barcode they got really mad :hehe:
