Full specifications, form factors and ordering FAQ: Kantech ioProx-compatible cards & fobs
Can Kantech ioProx P10SHL Clamshell Card cards be cloned?
Yes — Kantech ioProx P10SHL Clamshell Card is an open format that can be reproduced from its facility code and card number. We don't copy individual cards on request, though — we manufacture new, correctly-encoded credentials for the systems you own or manage.
125 kHz proximity — susceptible to electronic cloning with widely available hardware (Proxmark3, HID Omnikey, etc.). XSF dual-encoding provides broad code space but no cryptographic protection. Appropriate for standard commercial access control; not recommended for high-security environments without additional layered controls.

What is the read range of a P10SHL-compatible card on Kantech readers?
Read range depends on the reader model: up to 6.5 inches on P225/P225KP readers, up to 8.2 inches on P325/P325KP readers, and up to 29 inches on the P600 long-range reader when the card is presented parallel to the reader face.
Is the P10SHL a printable card?
The OEM P10SHL is a non-printable clamshell (the white polycarbonate shell is not dye-sub ready). If you need a printable ioProx card, the Kantech P20DYE or P30DMG are the printable variants; we offer compatible versions of those form factors as well.
Can I mix our compatible P10SHL cards with existing OEM Kantech cards on the same system?
Yes — our cards are encoded with the same XSF and 26-bit Wiegand formats as OEM P10SHL cards and are fully interchangeable on the same Kantech EntraPass system, provided the site code matches your existing credential database.
