A method for personalizing portable media such as cards having memory comprises writing personalizing data into each card (1) prior to its being put into service. For a mixed card, personalizing data are written onto the magnetic track (2) at the work station (P1), onto the card itself, for instance by stamping, at the work station (P2), and into the memory (5) of the card at the work station (P3).

A method of personalizing a standardized card embodying electronic microcircuits, including processing circuits and a memory, wherein personalizing data is written onto the card and into the memory of the card to enable both identification of an issuing organization of the card and of a user of the card, and to fix conditions and limitations of usage of the card, comprising the steps of prerecording, during manufacture of the card, a first manufacturer\s check digit into a secret zone of the memory which is inaccessible from outside of the card; constituting a central file by grouping together n groups of personalization data attributable respectively to n users; reading a first group of data from the central file and associating the data with the card to be personalized; extracting from the first group first data to be written into the card memory; calculating from the first data a second manufacturer\s check digit; comparing, within the card, the second check digit with the first check digit prerecorded into the secret zone of the memory; and invalidating the card if the first and second check digits are different; otherwise, writing the first data into the memory; extracting from the first group other data to be written onto the card; writing the other data onto the card; and repeating the foregoing steps automatically for (n-1) other groups of data to personalize (n-1) other cards.
