Wireless terminal to which an integrated circuit card is connected and a system utilizing the wireless terminal for rewriting memory of an integrated circuit card

摘要

An integrated circuit card memory rewriting system comprises an integrated circuit card with built-in memory and a wireless terminal having an interface for being electrically connectable with the integrated circuit card. A base station is called by the wireless terminal while the integrated circuit card is being electrically connected to the interface of the wireless terminal. Data relating to internal data stored in the integrated circuit card is requested from the base station. The wireless terminal then updates the data of the memory of the integrated circuit card connected to the interface using received signals transmitted from the base station.
