IEI / Linear 26-bit Proximity (HID-Compatible) Compatible Cards & Fobs
IEI/Linear 26-bit proximity cards are HID ProxCard II-protocol compatible credentials used throughout North American residential and commercial access control installations on Linear and IEI (Nortek Security & Control) hardware.
IEI (Identification Engineering Inc.) and its parent company Linear / Nortek Security & Control source their standard proximity credentials as HID-protocol 26-bit Wiegand cards — genuine HID OEM parts (e.g., 1386LGGMN) and compatible equivalents — making them fully interchangeable with the broader HID 125 kHz ecosystem. American Key Cards supplies IEI/Linear-compatible clamshell cards and key fobs pre-encoded to your facility code and card number range, at value pricing with no dealer-channel minimums.

Our compatible IEI / Linear 26-bit Proximity (HID-Compatible) credentials
American Key Cards manufactures non-OEM credentials engineered to work with your existing IEI / Linear (Nortek Security & Control) readers — no hardware changes, encoded to your facility code and card-number range.
Can IEI / Linear 26-bit Proximity (HID-Compatible) cards be copied?
IEI / Linear 26-bit Proximity (HID-Compatible) 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.
IEI/Linear proximity credentials use the standard HID 26-bit H10301 protocol with no cryptographic protection. Cards are readable and cloneable with any 125 kHz reader or Proxmark3. As these cards are HID-protocol compatible, they share the same clone vulnerability as all unencrypted H10301 cards.
Where IEI / Linear 26-bit Proximity (HID-Compatible) is used
- Replacement credentials for Linear and IEI access control panel installations
- Residential and light commercial door access
- Gate access systems using Linear controllers
- Multi-family housing access with Linear eMerge or IEI controllers

Are IEI/Linear proximity cards the same as HID cards?
Yes — IEI/Linear 26-bit proximity credentials use the same HID H10301 protocol and are fully interchangeable with HID 1326 ProxCard II cards at the reader level. Linear sources genuine HID cards (part numbers like 1386LGGMN) and rebrands them, so our HID-compatible cards work identically.
What facility code do I need for my Linear system?
Your facility code is set in the Linear or IEI access controller, not in the reader. It can be 0–255 for standard 26-bit Wiegand. Check your controller programming or look at your existing cards — the facility code is often printed on the label.
Will your cards work on a Linear eMerge Essential or E3 system?
Yes — Linear eMerge systems use standard Wiegand 26-bit (H10301) readers. Our IEI/Linear-compatible cards output the same 26-bit Wiegand data and are drop-in replacements on any Linear eMerge installation using 125 kHz proximity readers.
