Abstract:
A method for identifying a person authorized to enter into a secured transaction, including implementing a security system to receive a coded signal that purports to identify as an authorized person the wearer of a device generating the coded signal through a transmission link constituting the body of the wearer, upon physical contact between an input terminal of the security system and the body of the wearer. After purported identification of the wearer as an authorized person for the transaction, data stored in a memory of the device is delivered to assist in processing the transaction by access through the security system. Data stemming from the transaction is retrieved for updating data stored in the memory, usable in a subsequent transaction by the wearer. When a higher level of security is required for entry into the transaction, a predetermined physical characteristic of the wearer is scanned at the time the received coded signal purports to identify the wearer as an authorized person; and the scanned physical characteristic is then compared with a stored representation of the physical characteristic of the actual person identified by the coded signal to evaluate if a match exists. A personal identifier for a security system is also disclosed.
