An information processing system, an information communication terminal and method, an information processing device and method, a recording medium, and a program capable of safely performing electronic transaction. A store-for-purchase server (21) generates purchase information by using a card identification number assigned to a non-contact IC card of a mobile telephone (11). A store-for-reception server (31) acquires the purchase information and checks the card identification number assigned to the non-contact IC card of the mobile telephone (11) and the identification number of a purchase card. An authentication server (41) calculates a user reliability and a store reliability according to the temporary transaction information stored in the non-contact IC card of the mobile telephone (11). The user reliability and the store reliability calculated are referenced by the mobile telephone (11) and the store-for-purchase server (21) at the next transaction. The present invention can be applied to an electronic transaction service.
