How Proximity Cards Work

Proximity card readers translate the card code into a format the electronic door lock can understand. If the data on the card matches the list of valid key codes stored by the proximity system, the door will unlock. Proximity cards can’t be re-encoded, but the list of valid key codes recognized by the access control system can be updated as cards are issued, lost, or retired.

Proximity cards must be ordered from a secure supplier and cannot be encoded in house with an ID card printer; this prevents keycards from being fraudulently duplicated. Some organizations purchase a complete system that includes the cards and readers, or work with a security partner to install readers customized to your card type.
