A specific-accessible service and a commonly accessible service can co-exist while ensuring security with respect thereto. It is assumed that in a common area of a company A's issued IC card an electronic value corresponding to 1000 yen has been registered and a specific area of the common area has a specific-accessible service point of 50 (corresponding to 50 yen) registered. With respect to the commonly accessible electronic value and specific-accessible service point that are registered in the enterpriser A's issued IC card, addition and subtraction can be-both executed using a specific key A registered in the company A's terminal apparatus. However, in each of the respective co-operating 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 accessing right.
