The PAC OPS Grey Fob is a heavy-duty access credential built for environments where standard tokens don't last. Constructed from ABS plastic and ultrasonically welded into a fully sealed unit, it's the kind of fob that survives daily handling, exposure, and the general indignity of being on a keyring for years at a time. A metal eyelet makes keyring attachment straightforward — no clip required, nothing to break off.

Underneath that unassuming grey exterior sits a 4K MIFARE DESFire chip with a 7-byte unique serial number. That matters because DESFire encryption is specifically designed to resist credential cloning — a real concern in higher-security installations. These fobs are configured for use with the PAC GS3 Oneprox reader range and carry the manufacturer part number PAC-CD-FB-OPSC-NOC. Formerly listed as PAC 21102.

Supplied in a pack of 10. A sensible quantity for small rollouts, replacements, or supplementing an existing deployment without over-ordering.
