Title: Id card provided with magnetic storage part and sales management method using the card
Inventor: BANDO TOSHIYASU
IPC: G06Q50/10
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To make card utilization data into a data base even by a usual magnetic stripe reader-writer by recording the latest shopping date, the total number of shopping days, a total purchase amount and/or the number of points corresponding to the amount in a prescribed period in a magnetic storage part so that they can be rewritten. SOLUTION: A customer to whom an ID card 1 is issued signs a self-name in a signature column and shows the ID card 1 whenever the purchases a commodity. On a store side, a bar code reader reads a member number, and recognizes the authenticity of the card. A magnetic strip reader/writer reads the record content of a magnetic stripe 6 and writes new data. The latest coming date, the total of coming days and the total of purchase amounts in the prescribed period which is previously set are rewritten and recorded in the record content. The record content is decoded by the CPU of the magnetic stripe reader/writer at the time of update. It is printed/outputted, outputted data is preserved as sales data of respective members and it is used for sales management.

Title: Nonvolatile memory write processing method
Inventor: KISHI KOJI
IPC: G11C29/00
Filed: 1988-08-31
Abstract: PURPOSE:To increase the using efficiency of a write area by comparing write data with read data whenever writing is executed to a prescribed bank, judging that the life of the bank is expired at the time of discordance, and using the next tank. CONSTITUTION:First, the data are written by using a first bank out of the plural banks formed in a nonvolatile memory (EEPROM) 9, whenever the writing is executed, the data in an address are read, they are compared with the write data, when they are discordant, the first bank is judged to be expired, and the wall written data are shifted to the second bank, the data writing is executed by using the second bank from the next time, and thereafter the same processing as above is repeated. Thus, since the respective plural banks can be used until their lives are expired, the EEPROM 9 having the restriction of the number of times of rewriting can be efficiently used for a long time.
