     Access Control and Security Solutions for Every Application

The PSK-3 is a member of Keri’s Pyramid Series Proximity line of OEM readers, cards, and tags for access control.

The PSK-3 is one of the one of the smallest, most durable proximity credentials
available. Designed to be carried on a key ring, the PSK-3 is permanently
marked with a date code and ID number, includes a brass eyelet for added
strength, and is backed by a lifetime warranty – all at a very competitive

The PSK-3 is available with standard sequential encoding, and can be
programmed in any custom Wiegand™ format, as well as industry standard 26-bit Wiegand™.

Users have found the PSK-3 especially convenient for building entrances
where the user still has their car keys in hand. If the system has many
interior doors that are secured with Keri Pyramid Series proximity readers,
users often attach the tag to a necklace for easy carrying, especially
if their clothing does not have pockets.

Within the Pyramid Series Proximity line, the PSK-3 may be used interchangeably
with any other Keri credential or reader, including the P-300
Cascade Reader
, the P-400 Gibraltar Reader, the P-500 Alps Reader, and the P-600 Rocky Reader and Keypad. The Pyramid Series readers are all single piece design, offer lifetime warranties and industry standard Wiegand™ or magnetic stripe interfaces, and feature potted weather and vandal resistant construction, as well as optional HID compatibility.
