Can Honeywell / Northern N10002 34-Bit Prox cards be copied?

Honeywell / Northern N10002 34-Bit Prox 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.

The N10002 34-bit format is a legacy 125 kHz proximity technology with no cryptographic protection. Cards can be read and cloned using commercially available RFID tools (Proxmark3, handheld copiers). Honeywell Pro-Watch and related systems support upgrade to 13.56 MHz smart card credentials for environments requiring clone resistance.

Where Honeywell / Northern N10002 34-Bit Prox is used

  • Commercial buildings using Honeywell OmniProx reader series (PX4H, PX4H25)
  • Facilities using Honeywell Pro-Watch access control software
  • Replacement credentials for Northern Computers legacy installations
  • Phased upgrades where older OmniProx readers remain in service

Honeywell / Northern N10002 34-Bit Prox — FAQ

What is the Honeywell N10002 card format?

The N10002 is a 34-bit 125 kHz proximity format originally developed by Northern Computers (acquired by Honeywell) for their OmniProx reader series. It supports facility codes and card numbers each ranging from 0 to 65,535, providing a much larger card number space than the standard 26-bit format.

Are N10002 cards cloneable?

Yes. Like all standard 125 kHz proximity credentials, N10002-format cards operate without encryption and can be cloned with readily available RFID copier tools.

Is the N10002 format the same as the 40-bit Honeywell format?

No. The N10002 is a 34-bit format. Honeywell/Northern also produced a 40-bit format (sometimes referenced as C10106, used with GE CASI-RUSCO-compatible readers), which is a separate and less common format. The 34-bit N10002 is the primary Honeywell Northern standard.
