The EM4200 125KHz KeyFobs are the kind of access credential that just works — day after day, across a wide range of compatible readers, without asking anything of you or your users. Built from durable plastic with a waterproof construction, they're designed for real-world environments where credentials take a knock or two.
Fully compatible with EM4100, EM4200, and EM4105 communication protocols, these fobs slot into most 125KHz access control systems without any fuss. There's no battery to replace or manage — the fob draws what little power it needs from the reader itself, which keeps ongoing maintenance to a minimum and makes them a straightforward long-term credential choice.
Sold in packs of 100, with a standard loop for attaching to a keyring or lanyard, these are a practical bulk option for organisations issuing credentials at scale — whether for staff, residents, or site personnel.
