Kantech ioProx P10SHL Clamshell Card Compatible Cards & Fobs
The single most-replaced Kantech credential: the P10SHL clamshell — a rigid, slot-punched, dual-encoded (XSF + 26-bit) proximity card that anchors badge fleets across North American commercial buildings.

Every large EntraPass installation has a drawer that used to be full of P10SHL clamshells, because it is the default credential the system was commissioned with: rigid shell, strap slot, and the ioProx dual encoding that speaks Kantech's XSF to Kantech readers and standard 26-bit to everything else. When the drawer runs low, facilities face OEM channel lead times for what is, functionally, a programmed replacement card. That's the gap we close. Our P10SHL-style compatible clamshell matches the form factor — thickness class, slot punch, durability — and carries both encodings programmed to your fleet's numbering, verified on the bench before shipment. New cards enroll in EntraPass through your normal process and coexist with every original already in circulation.

What read range should I expect on Kantech readers?
Comparable to the original clamshell: several inches on standard mullion and single-gang ioProx readers, and substantially more on the P600 long-range unit. Exact range varies with mounting and environment, as it does for any passive 125 kHz credential.
Is the P10SHL style a printable card?
No — clamshells are too thick for ID printers, which is true of the category rather than any one brand. If you print photo badges, pair the clamshell fleet with printable ISO-body ioProx-compatible cards programmed identically; both run on the same system.
Can compatible clamshells mix with original Kantech cards on one system?
Yes. The panel reads the same XSF or 26-bit data from either, so mixed fleets are the norm. Continue your existing number sequence and the access-control records stay clean.
How do I give you the programming details?
Send the numbering from your EntraPass credential records or the printed values on current cards. We confirm the encoding — XSF plus the 26-bit identity — against a sample before production, so the batch arrives enrollment-ready.
