Keri Systems Proximité Compatible Cards & Fobs
Keri Proximité (PSC-1 credential family) is a 125 kHz proximity format used with Keri Pyramid Series readers, encodable in standard 26-bit Wiegand or custom Wiegand formats with a lifetime warranty on OEM cards.
Keri's Proximité line (PSC-1, PSC-1-A) are pre-programmed 125 kHz clamshell proximity cards built for Keri Pyramid Series readers, with each card's internal ID permanently marked on the back and options for 26-bit Wiegand, custom Wiegand, or magnetic-stripe encoding. Our compatible Proximité cards provide the same system interoperability at value pricing, without the OEM markup or minimum-quantity restrictions typical of authorized Keri channels.

What is the Keri Proximité format and how does it differ from Keri MS?
Keri Proximité (PSC-1 credential line) is designed for Keri's Pyramid Series proximity readers and can be encoded in 26-bit Wiegand or custom Wiegand formats. Keri MS format is a separate, earlier proprietary protocol exclusive to MicroStar readers. Proximité credentials are more universally Wiegand-compatible.
Can Keri PSC-1 cards be used on non-Keri access control systems?
Yes — when encoded in standard 26-bit Wiegand (H10301), Keri PSC-1 / Proximité cards work on any Wiegand-compatible access control controller, not just Keri systems.
Do Keri Proximité cards come pre-programmed?
Yes. OEM PSC-1 cards are sold pre-programmed with sequential codes and the internal ID printed on the back of each card. Our compatible versions are similarly pre-programmed to your specified site code and card number range.
