Card package production system card with insertion prevention and method

A card package production system with interchangeable inserters (A, B) and carrier folders (A, B) to enable use of forms (A, B) of different types verifies the carriers if they are properly produced and rejects them if they are not prior to the attachment to a carrier. The embossed characters and encoding read from the card are compared with the stored card data to verify accuracy and are compared to coding on the carrier form (A, B) to determine if there is a match. A code on the carrier is also compared to stored carrier data and to the cards provided for insertion and are rejected without cards if incorrectly prepared.
