What are Proximity Cards?

21st Feb 2017

A proximity card is simply an RFID (Radio-Frequency Identification) card that can be waved within the "proximity" of the reader without having to physically "touch" the reader, or swipe through the reader.  Proximity cards are typically used to gain access to a building, but in recent years provide the ability to logon or sign-in various software systems. Many systems utilize proximity technology. In theory, these systems utilize readers that extract the ID number from the card and convey that ID number to the controller. The controller then searches the database for validity of that number, and instructs the reader whether to "allow" or "deny" entry based on the validity of the ID number in the software. If the card number was not a valid enrollee in the system, access would be denied.  To enhance proximity card security even further, the controller can be set to read certain facility codes - in addition to only certain ID card numbers. This is a secondary level of authentication within the software itself. Thirdly, the controller could be programmed to allow only certain bit formats (in addition to the facility code and card number). This three-level configuration allows the maximum security within the proximity card platform.
