Proximity card devices consist of two components: a card reader and special cards attuned to specific transmission codes. The reader uses an antenna coil to send signals to the cards which receive the reader’s signal with its own antenna coil. Then it reflects the signal back to the reader with its unique code. At this point, the reader may verify or deny verification of the card’s code. Some Telephone Intercom Systems connect to the proximity detector.
