- FIG. 18 is a flowchart illustrating an operation procedure of the memory card 2 according to the second embodiment.
- the card control unit 212 acquires coupon data from the coupon server 3 via the data communication unit 211 (step S31). Further, the card control means 212 acquires, via the data communication means 211, the server time, which is the time information in the coupon server 3 at the time of acquiring the coupon, from the coupon server 3, and stores the server time as the coupon acquisition time data 225. It is stored in the section 22 (step S32). Further, the effective time at the time of acquisition of the coupon calculated by the coupon server 3 is acquired from the server 3 via the data communication means 211, and this effective time information is stored in the remaining effective time data at the time of acquisition of the coupon. It is stored in the storage unit 22 as the data 224 (step S33).
- the card control unit 212 acquires the current time of the mobile terminal 1 at the time of acquisition of the coupon as terminal time information via the data communication unit 211, and uses the terminal time information as the reference time data 223 in the storage unit 22. (Step S34).
- the card control means 212 monitors the force of the memory card 2 newly attached to the portable terminal 1 (step S35), and determines whether the time information of the portable terminal 1 has been changed. Monitor (step S36).
- step S35 When the memory card 2 is not newly inserted into the mobile terminal 1 (NO in step S35), and when the time information of the mobile terminal 1 is changed is not detected (N0 in step S36).
- the card control unit 212 periodically obtains the current time of the mobile terminal 1 (for example, once a day or once an hour) (step S37), and obtains a reference time from the current time of the mobile terminal 1.
- the data 223 is subtracted, and the used time of the coupon up to the current minute is calculated (step S38).
- the card control means 212 determines whether or not the obtained used time of the coupon up to the current minute is larger than the remaining valid time data 224, that is, the valid remaining time of the coupon (step S39). Here, if the used time of the coupon up to the current minute is larger than the remaining valid time data 224, the card control means 212 determines that the coupon has expired and performs the coupon expiration processing (step S40).
- step S39 when the used time of the coupon up to the current minute is equal to or less than the remaining valid time data 224, the card control means 212 determines that the validity period of the coupon has not expired, and Returning to the processing of step 2, the processing such as the detection of the attachment of the memory card 2 and the detection of the time change of the portable terminal 1 is repeated.
- step S35 If it is detected in step S35 that the memory card 2 has been inserted into the mobile terminal 1, the card control means 212 attempts to connect to the coupon server 3 (step S41). When the coupon server 3 cannot be connected, the coupon acquisition time data 225 stored in the storage unit 22 is delayed by an amount corresponding to the inability to connect to the coupon server 3 (step S42).
- step S43 The used time of the coupon is obtained by subtracting the value of the coupon acquisition time data 225 stored in the storage unit 22 from the current time of the coupon server 3.
- the card control unit 212 calculates the remaining effective time immediately after the memory card 2 is inserted, and updates the remaining effective time data 224 stored in the storage unit 22 with the obtained remaining effective time (step S44).
- the remaining valid time is stored in the storage unit 22 until the card is mounted, and is obtained by subtracting the used time of the coupon until the memory card is mounted from the value of the remaining valid time data 224.
