The PAC OPS Lite Blue Fob with Clip is a compact, fully sealed ABS token built for access control deployments where reliability under pressure matters. Running on 1K MIFARE Classic technology with a 4-byte serial number, it operates at high frequency and is compatible with PAC Ops Lite systems in CSN read mode — the kind of credential that quietly does its job across dozens of doors without asking for attention.

The sealed construction keeps out moisture and debris, making it a practical choice for environments that aren't kind to electronics. The included clip means users can attach it to a lanyard, bag, or keychain without needing additional hardware. It also incorporates design features that help reduce the risk of credential cloning — a consideration worth taking seriously in any access control refresh. Supplied in packs of 10.
