HID Prox H10302 (37-Bit, No Facility Code) Compatible Cards & Fobs
HID H10302 is a 37-bit proximity format with no facility code, providing over 34 billion unique card numbers for large deployments that need a flat, globally unique credential space.
H10302 transmits a single 35-bit cardholder ID with no facility code segmentation, making it ideal for enterprise deployments where administrators want to avoid facility-code conflicts across sites. American Key Cards programs H10302-format cards and fobs to your specified number range, fully compatible with any 125 kHz Wiegand reader set to 37-bit mode.

Our compatible HID Prox H10302 (37-Bit, No Facility Code) credentials
American Key Cards manufactures non-OEM credentials engineered to work with your existing HID readers — no hardware changes, encoded to your facility code and card-number range.
Can HID Prox H10302 (37-Bit, No Facility Code) cards be copied?
HID Prox H10302 (37-Bit, No Facility Code) is an open format, so a compatible card can be produced from your facility code and card number. We don't copy individual cards on request — we manufacture new, correctly-encoded credentials for systems you own or manage.
H10302 eliminates the facility code field entirely, giving a single 35-bit cardholder ID space supporting over 34 billion unique card numbers (0–34,359,738,367). This makes duplicate card numbers extremely unlikely across large deployments but does not add cryptographic security — cards can still be cloned with standard 125 kHz duplicators.
Where HID Prox H10302 (37-Bit, No Facility Code) is used
- Large enterprise campuses requiring unique card numbers without facility code management
- Healthcare facilities
- Government buildings using 37-bit compatible panels
- Deployments with Lenel, Software House, or Genetec panels supporting 37-bit

What is the difference between H10302 and H10304?
Both are 37-bit HID proximity formats. H10302 uses all 35 data bits for a single cardholder ID (no facility code), supporting over 34 billion unique numbers. H10304 splits the 37 bits into a 16-bit facility code and a 19-bit card number, similar in concept to the 26-bit format but with far more capacity.
Do standard HID proximity readers support the 37-bit H10302 format?
The physical readers are the same — any HID proximity reader operating at 125 kHz will receive the data. However, your access control panel must be configured to accept 37-bit Wiegand data; many older panels default to 26-bit and must be explicitly set to 37-bit mode.
Can H10302 cards be cloned?
Yes. H10302 cards use the same passive 125 kHz proximity technology as standard 26-bit cards and can be duplicated with commercially available handheld cloners. The larger card number space reduces the risk of accidental number collisions but does not prevent intentional cloning.
