Abstract
A method, computer program and system for alerting authorities during a transaction card authorization process, that a crime is in progress without alerting the perpetrator that an alert has been given. During a transaction card authorization process, the vendor attaches a code to the vendor identification sent to the authorization center. The code may be a normal code or a duress code. In either situation, the entered code is compared to the stored duress code. If a duress code has been entered, then the authorities are notified and the account transaction is approved, although at a slower rate than normal to provide authorities time to respond. Any attempt to contact the person under duress is delayed to avoid tipping off the perpetrator that an alarm has been sent.
