The PSC-1 is a member of Keri's Pyramid Series Proximity line of OEM readers, cards, and tags for access control.

At just 0.059 inches (1.5 mm) thick, the PSC-1 is up to 20% thinner than competing clamshell-type cards, making it more wallet friendly. In addition to the thin profile, dealers will appreciate the PSC-1's robust design backed by a lifetime warranty.

Available with standard sequential encoding, the PSC-1 can be programmed in any custom Wiegand™ format, as well as industry standard 26-bit Wiegand™.

Many users add dye sublimation printing of photos, images, and bar codes directly to the face of the PSC-1 through the use of Keri's PVC-9 PVC Adhesive Overlay.
