The invention provides a method that allows an issuer system, e.g. of a bank, to have generated a plurality of anonymous accounts and cards for working up a stock and to only personalize them individually if required. In the personalization step at the card issuer, e.g. in the bank branch, a printing of the back side does not have to be performed, instead all the necessary printing of the back side is already effected at the card manufacturer during the manufacturing of the anonymous card. As a result, a simple, low-cost printer without a back-side printing option can be utilized for the personalization of the anonymous card.
