How to use
Present the key fob to a compatible RFID proximity reader within the reader’s effective range; the reader will detect the transponder and grant or deny access according to the installed access control logic. No user configuration or power management is required. For enrollment, follow the access control system procedure to register the token’s identifier in the system database so it can be recognized by the reader.
Usage recommendations
Avoid exposing the key fob to strong mechanical impact or prolonged immersion in liquid to preserve the integrity of the housing and internal transponder. Store together with other keys but avoid placing in direct contact with strong magnetic fields or high-voltage equipment. Register and manage tokens through your access control software to maintain up-to-date user permissions.
