A plurality of services are defined for one service memory field (overlap service), and a plurality of access methods, such as "only read" and "read/write", are set in the service memory field. When an overlap service is defined, a PIN code may be set to each service. For example, when two services "read" and "read/write" can be started corresponding to a service memory field, two PIN codes are set.
