Gateway-based anti-theft security system and method
Improved systems and techniques are disclosed for controlling the security states of anti theft security systems such as product display assemblies using security fobs. The tasks relating to fob authentication are offloaded to a computer system, and these authentications can be based on identifiers for the different security fobs. The computer system can maintain a list of identifiers for authorized security fobs that is easily updated when new security fobs are added to or existing security fobs are de-authorized from the system.
1. A method for overriding a failed connection between a security fob and a computer system that authorizes security fobs to arm/disarm a product display assembly that displays a product, the method comprising:
wirelessly sending a fob identifier from a security fob that stores the fob identifier, a security code, and a finite number of override tokens to the computer system;
wirelessly sending the security code from the security fob to the product display assembly as a result of the security fob not receiving an authorization signal from the computer system;
changing the security status of the product display assembly from an armed state to a disarmed state or from the disarmed state to the armed state in response to the product display assembly receiving the security code from the security fob; and
decrementing the finite number of override tokens stored in the security fob;
wherein each override token of the finite override tokens authorizes the security fob to wirelessly send the security code to the product display assembly to control the security status of the product display assembly.
2. The method of claim 1 wherein the security fob does not send the security code when the finite number of override tokens is zero.
3. The method of claim 1 wherein wirelessly sending the security code comprises wirelessly sending the security code from the security fob to the product display assembly when the finite number of override tokens stored in the security fob is greater than zero.
4. The method of claim 1 wherein the finite number of override tokens correlates to a number of authorized uses available to the security fob when wireless communication between the security fob and the computer system fails.
5. The method of claim 1 further comprises inactivating the security fob when the finite number of override tokens equals zero.
6. The method of claim 1 further comprises renewing the finite number of override tokens by plugging the security fob into the computer system and issuing a renewed finite number of override tokens via a management portal of the computer system.
