Pyramid Series communicates via Wiegand or ABA Track II Magnetic Stripe (also known as clock and data) data interface formats. Today the Wiegand data format is the electronic access control industry's typical interface used to support communications between proximity readers and field control panels. Pyramid Series readers follow the Wiegand standard as specified in the Security Industry Association's (SIA) Access Control Standard Protocol for the 26-Bit Wiegand Interface document.

Pyramid Series cards and tags can be formatted in either the industry standard 26-Bit Weigand format or in any number of custom Wiegand formats. Within the industry standard 26-Bit Wiegand format Pyramid Series provides for a full implementation, affording customers the option of selecting the facility code (0 to 255 possible) and ID range (1 to 65,536 possible per facility code) required. Or for even quicker delivery we maintain a significant inventory of pre-programmed, 26-Bit Wiegand formatted PSC-1 Standard Light Proximity Cards, PSM-2 Multi Technology Proximity Cards, and PSK-3 Proximity Key Ring Tags ready to ship when needed.

Many customers opt for a custom Wiegand format because they need more facility codes and ID numbers, additional data fields (site code, city code, OEM code, etc.), enhanced security and/or heightened exclusivity. Custom Pyramid Series Wiegand formats can typically support up to 64-bits of customer definable data, though formats with larger bit counts are also available. As an added benefit and additional security, Keri tracks the unique coding of each and every custom formatted card and tag. If a system manufacturer, integrator or end user has an existing custom format with another card and reader manufacturer, we can normally match that format. And its important to note that we are happy to assist in the design and implementation of a custom Wiegand format at no additional charge.
