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.
Claims20
A print supply for a card personalization machine, the print supply comprising:
- a supply material used in a printing process of the card personalization machine;
- and
- a supply tag attached to the supply material, the supply tag including a memory storage that stores first supply tag data and a digital signature,
- wherein the rewritable memory storage is programmable to store a new digital signature and an updated authorized entity code upon authentication of an entity as an authorized entity and validation of the digital signature, and
- wherein the updated authorized entity code matches the print supply to the card personalization machine and the new digital signature secures the second supply tag data including the updated authorized entity code.
A method comprising:
- sending first supply tag data from a supply tag of a print supply at a card personalization machine to an issuance server, the first supply tag data including a first digital signature and a first authorized entity code;
- receiving an update from the issuance server upon in a memory of the supply tag, the update occurring upon authentication of an entity as an authorized entity and validation of the first digital signature, the update replacing the first authorized entity code with a second authorized entity code, the second authorized entity code being an updated authorized entity code that matches the print supply to a card personalization machine;
- wherein the memory of the supply tag further includes a new digital signature used to secure the second authorized entity code, the new digital signature being different from the first digital signature.
A print supply for a card personalization machine, the print supply comprising:
- a supply roll used in a printing process of the card personalization machine;
- and
- a supply tag attached to the supply roll, the supply tag including a rewritable memory storage that stores first supply tag data and a digital signature,
- wherein the rewritable memory storage is programmable to store a new digital signature and an updated authorized entity code upon authentication of an entity as an authorized entity and validation of the digital signature, and
- wherein the updated authorized entity code matches the print supply to the card personalization machine and the new digital signature secures the second supply tag data including the updated authorized entity code, the updated authorized entity code being unique to the authorized entity;
- wherein the supply tag includes a plurality of registers including a first register storing a unique serial number or part number of the print supply, a second register storing a property of the print supply, a third register storing the new digital signature, and a fourth register storing the updated authorized entity code.
