FAQ: About RFID Proximity Cards

FAQ: RFID Proximity Cards

Below is some information to help you understand RFID proximity cards:

How do RFID Proximity Cards Work?

Proximity cards are also called prox cards. They use a 125 kHz frequency to transmit a signal to a door access reader once the card is placed in proximity to the reader. When the card is placed on the reader, the card’s unique strand of numbers is passed to the access control panel, verifying if the number matches an approved card number (CSN) in the internal database.

What is the Difference Between a Proximity Card and a Smart Card?

Proximity Cards only store the facility code of the building or facility that the card should access and a card number. Smart cards are cable of storing this same information with the added ability to authenticate and store biographical information of the user.

What is 26-bit Wiegand?
26-bit is the industry standard for access control, representing an open encoding format. The data encoded using 26-bit format consists of 255 possible facility codes and within each there is a total of 65,535 unique card numbers. This is a relatively small number of unique cards, so additional authentication is often used.
How do I Know What Kind of Prox card I Have?  

Take a look for this information on the front or back of the proximity card you are using. There are many manufacturers of prox cards but each card should contain physical markings printed on the actual card itself.

Those markings will help you to determine the following:

  • The card manufacturer
  • The card format
  • The site and facility code
  • The card ID range number

If this information is not found on the card, you can also look at the label on the box of where your cards are stored or on the invoice from the card supplier.
