Abstract: An RFID telephone system that includes an RFID reader that reads RFID tags contained on wristbands worn by inmates. The system uses the RFID reader to monitor and control telephone calls conducted over the inmate telephone, including the creation of records associating each telephone call with a particular inmate identifier read from an RFID tag in connection with the telephone call. The RFID reader obtains an authorized inmate identifier read from an RFID tag placed in close proximity to the inmate telephone and enters the inmate identifier in a record that associated that inmate identifier with the telephone call. The RFID telephone system inserts the personal identifiers read from RFID tags into the CLID field of a calling directory number service, and may also include a local call monitoring system that stores the personal identifiers in association with audio recordings of the telephone calls.
