Abstract
A specific-accessible service and a commonly accessible service can co-exist while ensuring the security thereof. It is assumed that a common area of a company A's issued IC card has registered therein an electronic value (corresponding to 1000 yen and a specific area thereof has registered therein a specific-accessible service point of 50 (corresponding to 50 yen). With respect to the commonly accessible electronic value and specific-accessible service point that are registered in the enterprise A's issued IC card, addition and subtraction can both be executed using a specific key A registered in the company A's terminal apparatus. However, in each of the respective cooperating companies' terminal apparatus, with respect to the commonly accessible electronic value, only subtraction processing is possible using a common key registered therein. But, to the processing that is executed with respect to the specific-accessible service point registered in the specific area, that terminal apparatus has no access right.
