Kantech ioProx (XSF / 26-bit) Compatible Cards & Fobs

Kantech ioProx is a dual-encoded 125 kHz proximity format (proprietary XSF + standard 26-bit Wiegand) used widely across North American commercial buildings on Johnson Controls / Kantech EntraPass access control systems.

The Kantech ioProx credential line operates at 125 kHz and encodes two formats simultaneously on every card or fob: Kantech's proprietary XSF (eXtended Secure Format) for ioProx-native readers, and standard 26-bit Wiegand for backward compatibility with any Wiegand controller. Our compatible cards cover the full OEM form-factor range — clamshell cards (P10SHL-style), key tags (P20WLM/P40KEY-style), and printable PVC cards (P30DMG-style) — at value pricing with no minimum-quantity OEM restriction.

Can Kantech ioProx (XSF / 26-bit) cards be copied?

Kantech ioProx (XSF / 26-bit) 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.

125 kHz proximity — readable and cloneable with commercially available tools (Proxmark3, T5577 blanks). The XSF dual-encoding provides broader code space than standard 26-bit but does not add cryptographic protection. Upgrade to 13.56 MHz smartcard credentials for environments requiring clone resistance.

Where Kantech ioProx (XSF / 26-bit) is used

  • Commercial office buildings on Kantech EntraPass systems
  • Multi-tenant residential access control
  • Retrofit badge replacements for existing ioProx reader installations
  • Government and institutional facilities using Kantech infrastructure

Kantech ioProx (XSF / 26-bit) — FAQ

Are your ioProx cards compatible with Kantech EntraPass systems?

Yes. Our ioProx-compatible cards are dual-encoded with both Kantech XSF and standard 26-bit Wiegand, making them drop-in replacements on EntraPass and any Wiegand-based system using ioProx readers.

What is the difference between XSF and 26-bit Wiegand on a Kantech ioProx card?

XSF (eXtended Secure Format) is Kantech's proprietary encoding that supports over 4 billion unique codes using a Family Code, Facility Code, and Card Number. Standard 26-bit Wiegand supports only ~65,000 card numbers per site code. Both formats are stored on every ioProx credential simultaneously.

Can Kantech ioProx cards be cloned?

Yes — like all 125 kHz proximity cards, ioProx credentials can be read and copied with tools such as Proxmark3 and T5577 blank cards. If clone-resistant credentials are required, Kantech also supports 13.56 MHz smart card readers.
