Key fobs can be reprogrammed to allow only employees to enter the building. It also allows you to control who and when can enter which doors. For example, you can restrict access to a warehouse to only those employees who need it during their assigned work hours.

Anti-hacking system - RFID-blocking sleeves for key fobs are available. This safeguards your key fob against malicious individuals attempting to hack your data. You can also set your system to non-broadcast mode. This generates a challenge-response approach or rolling code that prevents a hacker's reader from working. In the event of unauthorized access, it automatically executes some codes that protect sensitive data and block hackers.
