The 26 Bit H10301 format has been the industry standard for low-frequency 125 kHz access control credentials for over three decades. Known for its simplicity, cross-compatibility, and reliability, this open Wiegand format remains one of the most widely used credential types in North America.
At Secure It Controls, we specialize in supplying, programming, and installing H10301 26-bit low-frequency proximity cards, key fobs, and tags that integrate seamlessly with most commercial access control systems.
What Is the 26 Bit H10301 Format?
The H10301 is a Wiegand 26-bit data format that encodes identification data across 26 bits of binary information. Its structure is simple yet effective:
- 1 leading parity bit (odd)
- 8 bits for facility code (range 0–255)
- 16 bits for card number (range 0–65,535)
- 1 trailing parity bit (even)
This straightforward structure allows virtually any Wiegand-based system to interpret the data, making the 26 Bit H10301 format universally recognized and supported across thousands of 125 kHz readers worldwide.
Why the 26 Bit H10301 Format Remains the Industry Standard
Universal Compatibility
The 26 Bit H10301 format is compatible with nearly all 125 kHz Wiegand readers and controllers, including systems from HID Global, AWID, Farpointe Data, Keri Systems, DSX, Brivo, Linear, Paxton, and SecuraKey (dual-format models only).
This universal interoperability makes H10301 the ideal choice for both system expansions and retrofits.
Proven Reliability
The format’s long track record and low error rate make it a dependable option for organizations requiring consistent credential performance. It’s also ideal for environments where card replacement, re-issuance, or multi-site use is common.
Flexible Credential Types
Because it’s based on open-standard encoding, the H10301 format can be programmed into clamshell cards, printable PVC cards, adhesive tags, and key fobs, giving end users a wide range of credential form factors without changing reader infrastructure.
