key cards

Room entry slips

Key cards are plastic cards that unlock doors electronically, replacing traditional metal keys in hotels, offices, and secure buildings.

The card stores data on a magnetic stripe or chip that a reader recognizes: I forgot my key card and had to go back to the front desk.

Key cards can be programmed to grant access only to specific areas or during certain hours.
