Inserter system for RFID cards

In an inserter control system (27), RFID signals of RFID enabled cards are related to mail pieces in a mail piece production database. The RFID enabled cards are fed into the inserter system from a card feeder (22). An attaching device attaches the cards to a carrier sheet. The assembled mail pieces are then inserted (6) into envelopes to form finished mail pieces. Sensors (4) are located within the system to detect the RFID signals. The sensed RFID numbers are compared with stored mail piece data. The system is programmed to process the mail piece based on instructions in the database. If a sensed RFID signal does not match the RFID number that is expected for a particular mail piece that is expected at a location of the sensing, then the system generates an error signal.
