Failure handling method for IC cards

Abstract

Abstract PURPOSE:To reduce a burden of a host device, and to shorten the data processing time by allowing an IC card itself to execute a detection for a fault and its processing, when a fault has been generated in a memory in the IC card. CONSTITUTION:An IC card is provided with a spare area 18, a data collating part 15, and a memory managing part 14. A piece of write data which has been sent from a host device 10 is written in a data storage part 17. Thereafter, whether the data has been written normally or not is inspected by the data collating part 15. In case the data has not been written normally, said part is replaced with the spare area 18 automatically by the memory managing part 14.
