Explanation
According to the PCI Card Production and Provisioning - Logical Security Requirements, there must be a clear segregation of duties between the staff involved in different card production and provisioning activities, such as card personalization, PIN generation and printing, and card fulfillment. This is to prevent any unauthorized access, modification, or disclosure of sensitive cardholder data and to ensure the integrity and confidentiality of the card production process. Therefore, if John is involved in card personalization, which is the process of transferring cardholder information to a payment card, then he must never be involved in PIN printing, which is the process of printing the personal identification number associated with the cardholder account on a mailer. This way, John cannot link the cardholder data on the card with the PIN on the mailer, and cannot compromise the security of the cardholder authentication. The other statements are not true, as there is no requirement that prohibits John from being involved in the card shipment process, as long as he does not have access to both the card and the PIN mailer at the same time.
