Proximity Access Control

Proximity access controls incorporate a radio frequency reader and users carry a card or key fob which they swipe in front of the reader to allow access to the building.

Cards and key fobs can be added or removed from the system by means of master cards, or directly at the access panel by programming and swiping the card in question. A keypad programmer, which simulates a card, can also be used to programme proximity access control panels.

The most common frequencies in proximity access systems are MIFARE (13.56MHz) and EM (125KHz). This is very important as these technologies are not compatible with each other, i.e. you cannot use a MIFARE reader for EM cards/keyfobs (and vice versa); therefore both the reader and the cards/keyfobs must be of the same technology.
