Have Questions about HID Proximity Cards? We Have Answers!

Both 26 bit and 37 bit HID cards are low frequency, 125 kHz cards, in fact, they even look identical on the outside. The difference in the cards is in the programming, specifically related to the facility code and card numbering.

26 bit proximity cards
  • Are also known as format H10301 cards, 26 bit cards are the most common type of proximity card
  • When placing an order for 26 bit H10301 cards, specify your facility code & card start number
  • You are in complete control of tracking the card numbers used in each of your facilities
  • There is a risk of duplicating card numbers in 26 bit cards, especially when multiple locations place
  • card orders or staff changes
37 bit proximity cards
  • Are also known as format H10302 cards
  • Because HID manages the card numbers, you don't need to specify facility code or card start number
  • HID controls card numbering, guaranteeing that card numbers are never duplicated across ALL 37 bit cards
  • You will be ensured that no card numbers are ever duplicated
  • Note: card numbers will be sequential on a single order, but there will be gaps in numbers across your entire inventory of cards
40 bit proximity cards
  • Are also known as Casi Rusco format C10106 cards.
  • Because HID controls card numbering, you do not need to specify start numbers.
  • Since HID controls card numbering, there is no risk of duplicating card numbers.
  • Note: card numbers will be sequential on a single order, but there will be gaps in numbers across
  • your entire inventory of cards

There are three primary factors that affect compatibility between HID proximity cards and HID proximity card readers.

The reader must be capable of reading the card frequency. For example, the pcProx Plus Enroll Prox Card Reader can read 125 kHz prox cards and 13.56 MHz contactless cards.   Some readers are programmed to only read specific formats. (i.e. 26 bit, 37 bit, etc.)   Some readers are programmed to only read a proprietary card that must be reordered from the original proximity program provider.  

While you can look at your card reader's specifications, the best way to ensure compatibility is to reorder the same HID proximity cards with the same configurations. This information is often found on the packaging from the original cards. If you are unable to locate this information, call an ID Professional at (800) 321-4405. We're happy to help!
