System and method for controlling access to designated area
First Claim
1. A system for controlling access to a designated area, the designated area having a security device to control access thereto, comprising:
- a programmable unit to generate a first and second key for each access to the designated area;
a programming unit to generate an access key using the first key;
a programmable tag to store the access key; and
a validation system including a control unit to generate a validation key using the second key, a memory to store the validation key, and a communication device to establish a data communication with the programmable tag to receive the access key therefrom, the control unit comparing the access key and the validation key and causing the security device to allow access to the designated area if the access key matches the validation key.

Abstract
A system and associated method for controlling access to a designated area. The system includes a programmable unit, a programming unit, a programmable tag, and a validation system. The programmable unit generates a first and second key for each access to the designated area. The programming unit generates an access key using the first key. The programmable tag stores the access key. The validation system includes a control unit, a memory, and a communication device. The control unit generates a validation key using the second key. The memory stores the validation key. The communication device establishes a data communication with the programmable tag to receive the access key therefrom. The control unit compares the access key and the validation key and causes the security device to allow access to the designated area if the access key matches the validation key.
