Product DescriptionProduct Details & Description

125KHz EM proximity is the legacy and value-tier access control credential technology. It has been widely used in UK door entry and access control systems for over two decades and remains in use in many installed systems. A 125KHz fob contains a passive RFID chip that transmits its fixed unique ID to compatible readers.

The key fob form factor is the most convenient credential for attachment to a keyring or lanyard: the small flat body and ring attachment make it easy to carry with other keys and present quickly to the reader.

Important credential selection notes for installers: 125KHz EM fobs are not compatible with Mifare (13.56MHz) readers such as those used by Dahua access control and most modern higher-security readers. The frequency and protocol are different. Systems running Mifare readers require Mifare cards or fobs (such as the Dahua ic-s50 Mifare card). Ajax systems use their own proprietary tags, which are also different.

The blue colour of this fob is the product's standard colour from the manufacturer and does not carry a specific access level meaning in the way that some colour-coded credential systems use colour to indicate user type.

For installers and facilities managers completing 125KHz access control credential orders across London and the UK, the blue 125KHz fob provides the standard EM proximity credential for compatible readers.
