FORT COLLINS, CO — AuthorizID, Northern Colorado’s source for access control credentials, now offers free access card format identification for businesses, property managers, HOAs, schools, healthcare facilities, warehouses, and security integrators. Customers can mail in a working card or key fob, or send photos. AuthorizID will identify the format, facility code, and card number, then match it with compatible replacement credentials.
Ordering the wrong format is one of the most common and expensive mistakes in access control. A card can look exactly like the one you already have and still not work on your reader. AuthorizID’s free identification service takes the guesswork out of reordering, so facilities can expand or replace credentials without new readers or panels.
Why Your Card Format Matters
A working replacement credential has to match three things: the format (the bit structure and data layout, such as 26-bit H10301 or HID Corporate 1000 35-bit), the facility code that identifies your site, and the card number assigned to each user. If any of the three is wrong, the card won’t open the door.
Many cards don’t make this easy. Some proximity cards don’t print the facility code, printed numbers may not match the internal encoding on extended formats, and older cards and fobs are often worn or unmarked.
How to Identify Your Card Format
AuthorizID has published a step-by-step guide that walks customers through the process themselves:
- Check the frequency: 125 kHz proximity or 13.56 MHz smart card. A smartphone NFC app can give a quick first clue.
- Read the printed markings on the back or edge of the card or fob.
- Match those markings to a known format.
- When the card is blank, check the original box, your access control software, or the reader and panel models.
- Choose the right form factor, then send a sample or photos if you’re still unsure.
