Programmable security system and method for protecting merchandise

Abstract

A programmable security system and method for protecting an item of merchandise includes a programming station, a programmable key and a security system. The programming station generates a security code and communicates the security code to a memory of the programmable key. The programmable key initially communicates the security code to a memory of the security device and subsequently operates the security device upon a matching of the security code in the memory of the security device with the security code in the memory of the programmable key. The programmable key may also transfer power via electrical contacts or inductive transfer from an internal battery to the security device to operate a lock mechanism. The security code may be communicated by wireless infrared (IR) systems, electrical contacts or inductive transfer. A timer inactivates the programmable key and / or the security device after a predetermine period of time. A counter inactivates the programmable key after a predetermined maximum number of activations.

AI Technical Summary

Benefits of technology

The present invention provides a security system and method for protecting items of merchandise by using a programmable key with a unique security disarm code (SDC) that can only be activated in a specific retail store. The key is programmed with the SDC by a programming station and remains active for a predetermined period of time. The key is designed to be reprogrammed with a new SDC after a certain period of time to prevent unauthorized use. The security system includes various features such as internal timers, indicators, and logic control circuits to ensure the security of the system. The invention also provides a wireless communication system for data communication between the key, programming station, and security devices.

Problems solved by technology

A known problem with such security systems is that the keys may be stolen from the retail store and used at the same store or at another store using the same type of alarm module or other security device, to enable a shoplifter to disarm the alarm module or to unlock the security device from the merchandise.

Keys may also be stolen by a dishonest employee and used by the employee in an unauthorized manner or passed to a shoplifter for use at the same store or at another store having the same type of alarm module or security device controlled by the key.

It is extremely difficult to prevent the theft of security system keys by shoplifters or dishonest employees within a retail store due to the large number of keys that must be made available to store personnel in various departments of the store to facilitate use of the numerous alarm modules and other security devices needed to protect the valuable items of merchandise on display in the retail store.
