Method and System for Controlling Smartcards

摘要

This invention relates to a method and system for controlling smartcards 300 which are capable of audiovisual output. Data stored 304 remotely from the smartcard is monitored for indication of a predetermined criterion, for example indication of a certain level of funds in a smartcard user's bank account. A control signal can then be communicated to the smartcard for controlling the update of audiovisual output from the smartcard. The control signal can thus be communicated to the smartcard in response to a trigger generated externally of the smartcard. Data relating to audiovisual output of the smartcard may be stored on the smartcard itself, in which case the control signal may indicate to the smartcard to update its audiovisual output according to audiovisual data already present on the smartcard.
