Keri Systems PSK-3 Pyramid Series Proximity Key Ring Tag, RFID Tag, 50-Pack

Make secure entry effortless for employees and visitors with the Keri Systems PSK-3 Pyramid Series proximity key ring tag. This 50-pack of RFID tags delivers a compact, reliable credential that mounts easily to keys or lanyards, helping speed traffic through monitored doors and reduce access friction at building entrances. Each PSK-3 is built from rugged ABS with a brass eyelet and a 0.15" thickness, offering wash-resistant durability and a lifetime warranty that lowers long-term operating costs.

Operating at 125 kHz and available with standard 26-bit Wiegand or custom Wiegand formats, the PSK-3 integrates smoothly with Keri Pyramid Series readers and most third-party access control systems, making it ideal for security, surveillance, and facility monitoring applications. At just 1.18" x 1.5", the credential is unobtrusive but highly functional for everyday use. Sold in a 50-pack (PSK-3-50), these tags simplify bulk rollouts for offices, healthcare sites, education campuses, and multi-tenant facilities.
