Abstract
A method for providing remote programming of a supply tag of a print supply used with an authorized entity's card personalization system is provided. The method includes an issuance server authenticating remote programming of the supply tag, receiving first supply tag data of the print supply including a first digital signature, updating the first supply tag data to obtain second supply tag data, and issuing a second digital signature based on the second supply tag data. The second digital signature secures the second supply tag data.
