摘要：
A multi-stage verification system including a first and second identification device to verify the identity of the user and to determine if the user is under duress. When a user approaches an entrance to a building, a first identifier is detected by the first identification device, the identifier is compared to a pre-stored identifier. If there is a match, the user inputs at least one biometric input into the second identification device. The biometric input is compares with pre-stored information in two different databases, a biometric template database and a duress indicator database. If there is a match with the duress indicator database, a silent alarm signal is transmitted to a central monitoring station and the security system is disarmed. If there is a match with the biometric template database, the security system is controlled in the intended manner.
