Method and system for storing tickets on smart cards

A method of registering tickets on a smart card including a memory, comprising the steps of:

• creating a ticket in the memory, the ticket including at least one field;
• issuing the ticket by storing in the at least one field data identifying a right to be conveyed by the ticket;
• wherein the step of issuing the ticket comprises using a first command for setting and resetting bits, and a second command for only setting bits, the first command being operational exclusively in response to an identification of a first type of terminal;
• and
• storing the data in the at least one field using a code containing a fixed number of set bits per group of bits.

A system for providing access to services, comprising:

• at least one smart card, including,
• a memory for storing tickets comprising at least one field;
• and
• at least one terminal including at least one of an issuing, validating, and verification terminal;
• wherein the issuing terminal of the at least one terminal is configured to store in the at least one field data representing the right to access a service, and the data in the at least one field is stored using a code containing a fixed number of set bits per group of bits;
• and
• wherein the smart card is configured to respond to a first command for setting and resetting bits, and a second command for only setting bits, the first command being operational exclusively in response to an identification of the issuing terminal.
