Abstract
In a method for preventing unauthorized credential substrate processing in a credential production system that includes first and second credential production components, a first security code is generated using a random code and a first security key with the first credential production component. The first security code is communicated from the first credential production component to the second credential production component. The validity of the first security key is then checked using the first security code, the random code and a second security key with the second credential component. Finally, processing of the credential substrate by the credential production system is prevented when the first security key is not valid.
