Abstract
A system for authorizing smart cards via the Internet is provided, comprising a plurality of user stations (1-1-1-n) connected to a server (3) via the Internet (5) . Each of the user stations (1-1; 1-n) is attached to a card reader (7-1;7-n) suitable for reading data and accessing processing modules on smart cards (8-1-8-m). When a new card is to be issued, initially the server (3) generates and stores a task identifier as a task record (15) on a database (10) connected to the server (3). The task identifier is also dispatched to a user station (1-1; 1-n). A subsequent data submission by the user station (1-1; 1-n) is then required to include signed data incorporating authorization data and the received task identifier. When all the data required for authorization of a smart card (8-1; 8-m) has been received, the server (3) checks the signed data to confirm each data submission comprises data incorporating a correct task identifier utilised for the current authorization procedure.
