If you manage access control systems across Colorado, chances are you’ve encountered the Kantech ioProx XSF 26-bit format. It’s one of the most reliable proximity credential formats in the industry—favored for its security, scalability, and compatibility with Kantech door controllers and readers. At Secure It Controls, we specialize in programming, installing, and maintaining ioProx XSF systems for businesses and properties in Fort Collins, Loveland, Greeley, Longmont, Boulder, Brighton, and Denver.

1. What Is the Kantech ioProx XSF 26-Bit Format?
The Kantech ioProx XSF 26-bit format is a proprietary card data structure developed by Kantech, part of the Tyco/Johnson Controls family. It uses Wiegand-based communication between readers and controllers, encoding both a site code (or facility code) and a unique card number for every credential.
Each XSF card transmits 26 bits of data, which are interpreted by compatible Kantech readers and controllers such as the KT-1, KT-300, and KT-400. The result is reliable, traceable access control across multiple buildings and entry points.
2. Programming ioProx XSF Credentials
Kantech ioProx cards can be ordered pre-encoded or programmed in-house using a Kantech encoder or compatible badge printer. When ordering or programming, you’ll need to specify:
- Facility (Site) Code – a number unique to your organization or building group
- Card Number Range – sequentially assigned to each user
- Bit Length – 26-bit is the most common, but Kantech also supports 32-bit and 40-bit variants
For property managers or IT administrators, keeping an updated record of these values ensures accurate credential assignment and easy replacement when cards are lost or reissued.
3. Reader and Controller Compatibility
The ioProx XSF format is compatible with Kantech readers such as the P225KP, P325KP, P345KP, and P600KP models. These readers support both standard proximity credentials and Kantech XSF encoded cards.
Many third-party readers (like HID or Farpointe Pyramid) may read ioProx cards but cannot decode the proprietary Kantech data. That’s why installations using ioProx credentials should always pair with verified Kantech reader hardware for consistent performance.
At Secure It Controls, we install and service ioProx reader systems across Fort Collins, Loveland, Greeley, Longmont, Boulder, Brighton, and Denver, helping commercial and multifamily properties maintain secure, centralized control over access points.
4. Understanding Site Codes and Access Levels
Each ioProx XSF credential includes a site (facility) code — this acts like a unique building identifier. It prevents duplicate card numbers from being accepted across multiple organizations.
For example, if two cards share the same user number but different site codes, the system can differentiate between tenants or campuses. This feature is especially valuable in multi-building complexes and corporate facilities with multiple locations throughout Northern Colorado.
5. Upgrading or Expanding Your ioProx System
Many businesses expand their systems over time by adding new doors, readers, or buildings. The ioProx format supports straightforward scalability.
Secure It Controls can help integrate your Kantech ioProx readers with modern access platforms, networked door controllers, or additional credential types such as key fobs, wristbands, and adhesive tags — all while maintaining the same XSF site code for continuity.
