keycards
Electronic door openers
Keycards are flat, credit-card-sized cards used to unlock doors or access secured areas.
Hotels issue keycards to guests; offices use them to control building entry.
The card contains a magnetic stripe, chip, or RFID technology that communicates with a reader: I forgot my keycard and got locked out of the room.
