Abstract

To provide an electronic information storage medium, an IC chip, an IC card, a response transmission method, and a program capable of easily identifying the cause of an error when an error occurs during issue processing for writing a plurality of data into a memory.SOLUTION: When an issue command is received from an external device 2, an IC chip 1 determines whether a predetermined issue rule is satisfied or not, and when it is determined that the issue rule is not satisfied, transmits a response including a status word indicating that the issue rule is not satisfied and a DGI of data not satisfying the issue rule to the external device 2.SELECTED DRAWING: Figure 3
