Kantech ioProx (XSF / 26-bit) Compatible Cards & Fobs
Kantech's dual-personality credential: the proprietary XSF format for EntraPass systems and a standard 26-bit Wiegand encoding on the same card — one credential that speaks both languages, all over North American commercial buildings.

The clever part of the ioProx design is the dual encoding. Every credential carries Kantech's own XSF — the eXtended Secure Format that EntraPass systems use, with a 64-bit code space that makes fleet-wide numbering effortless — and simultaneously a standard 26-bit Wiegand identity for third-party readers and panels. That is why an ioProx card can open a Kantech-controlled headquarters and a generic 26-bit parking gate with the same tap. Facilities on EntraPass replace these credentials constantly as tenants and staff turn over, and OEM channel ordering can be slow for small batches. We supply unbranded, ioProx-compatible cards and key tags programmed to your XSF and 26-bit values — matched to your existing enrollment records so they register in EntraPass exactly like the credentials you already issue, with both encodings verified before shipment.

Are your ioProx-compatible cards recognized by EntraPass systems?
Yes — they present the same XSF data structure that EntraPass reads from any ioProx credential, so enrollment follows your normal process. We program them to the values you specify and verify the encoding before shipping.
What's the difference between XSF and the 26-bit encoding on the same card?
XSF is Kantech's own format with a much larger code space, used when the card talks to Kantech readers on an EntraPass system. The 26-bit Wiegand encoding is the universal fallback that generic readers and panels understand. The card carries both at once, which is what makes mixed environments work.
Which part-number styles can you replace?
The common ioProx family — clamshell cards (P10SHL style), printable cards, and key tags (P40KEY style). Tell us which form factors you issue and we match them; the programming is identical across bodies.
What do you need from me to program a batch?
Your current numbering details — the values shown in your EntraPass credential records or printed on existing cards — plus quantity and form factor. If you're unsure how your fleet is numbered, photos of a current card plus a screenshot of its EntraPass entry are enough for us to confirm the specification.
