Abstract

A certifying system for checking validity of a radio tag passing through a predetermined route includes a route information writing section that writes information relating to a route passed by the radio tag on the radio tag, a route information acquisition section that acquires information relating to the route written on the radio tag by the route information writing section, a storage section that stores information relating to a regular route preset corresponding to the ID of the radio tag, and a certifying section that checks the validity based on the information relating to the route written on the radio tag acquired by the route information acquisition section and the information relating to the regular route stored in the storage section.

Claims

1. A certifying system for checking validity of a radio tag passing through a predetermined route comprising:

a route information writing section, disposed along the predetermined route, that writes information relating to a route passed by the radio tag on the radio tag,

a route information acquisition section that acquires the information relating to the route written on the radio tag by the route information writing section,

a storage section that stores information relating to a regular route preset corresponding to the ID of the radio tag, and

a certifying section that checks the validity based on the information relating to the route written on the radio tag acquired by the route information acquisition section and the information relating to the regular route stored in the storage section.

2. The certifying system according to claim 1, wherein

the information relating to the route passed by the radio tag includes the information relating to the passing spot of the radio tag.

3. The certifying system according to claim 1, further comprising:

an NG flag writing section that writes an NG flag for inhibiting the use of the radio tag not permitted for the certification in the certifying section, wherein

the certifying section does not permit the certification for the radio tag written by the NG flag.

4. The certifying system according to claim 1, further comprising a gate lock control section that unlocks and locks a gate installed on the predetermined route, wherein

the gate lock control section locks the gate if the certification is not permitted in the certifying section.

5. The certifying system according to claim 1, further comprising:

a period-of-validity information writing section that writes a period of validity of the radio tag on the radio tag, wherein

the certifying section does not permit the certification for the radio tag of which the written period of validity expired.

6. The certifying system according to claim 1, further comprising:

a password information setting section that sets password information for taking the permission of the certification in the certifying section,

a password information writing section that writes password information set by the password information setting section on a radio tag,

a password information acquisition section that acquires the password information written on the radio tag by the password information writing section, and

a password information input section that inputs password information used for comparing with the password information set by the password information setting section, wherein

the certifying section certifies based on password information written on the radio tag acquired by the password information acquisition section and password information input by the password information input section.

7. A radio tag comprising a radio antenna and a memory section, and capable of being accessed by a radio signal from a read-write unit arranged along a predetermined route, wherein

the memory section stores information relating to the route passed by the radio tag written by a read-write unit.

8. A certifying method comprising:

a route information writing step of writing information relating to the route passed by the radio tag to the radio tag disposed along a predetermined route and passing the predetermined route,

a route information acquiring step of acquiring information relating to the route written on the radio tag in the route information writing step, and

a certifying step of certifying based on information relating to the route written on the radio tag acquired in the route information acquiring step and information relating to the regular route preset corresponding to the ID of the radio tag.

9. The certifying method according to claim 8, wherein the information relating to the route passed by the radio tag includes information relating to the passing spot of the radio tag.

10. The certifying method according to claim 8, further comprising:

an NG flag writing step of writing an NG flag for inhibiting the use of the radio tag not permitted for the certification in the certifying step, wherein

the certifying step does not permit the radio tag with the NG flag written.

11. The certifying method according to claim 8, further comprising:

a gate lock control step of unlocking and locking a gate installed on the predetermined route, wherein

the gate lock control step locks the gate if the certification is not permitted in the certifying step.

12. The certifying method according to claim 8, further comprising:

a period-of-validity information writing step of writing a period of validity of the radio tag on the radio tag, wherein

the certifying step does not permit the certification for the radio tag of which the written period of validity expired.

13. The certifying method according to claim 8, further comprising:

a password information setting step of setting password information for taking the permission of the certification in the certification step,

a password information writing step of writing the password information set by the password information setting step on the radio tag,

a password information acquiring step of acquiring the password information written on the radio tag by the password information writing step, and

a password information inputting step of inputting the password information used for comparing with the password information set by the password information setting step, wherein

the certifying step certifies based on the password information written on the radio tag acquired by the password information acquiring step and the password information input by the password information inputting step.

14. The certifying method according to claim 8, further comprising:

a position information writing step of writing the information relating to the present position of the radio tag on the radio tag, and

a process permitting step of permitting only a predetermined process to be permitted at the present position based on the information relating to the present position written on the radio tag.

15. A certifying program allowing a computer to execute:

an information acquiring step of acquiring information relating to a route passed by the radio tag and written on the radio tag,

a certifying step of certifying based on the information relating to the route written on the radio tag acquired by the information acquiring step and the information relating to a regular route preset corresponding to the ID of the radio tag, and

a route information writing step of writing the information relating to the route passed by the radio tag to the radio tag permitted by the certification in the certifying step.

16. The certifying program according to claim 15, further comprising an NG flag writing step of writing the NG flag for inhibiting the use to the radio tag not permitted for the certification in the certifying step, wherein the certifying step does not permit the certification for the radio tag with the NG flag written.

17. A certifying program allowing a computer to execute:

an information acquiring step of acquiring the information relating to the route passed by the radio tag and written on the radio tag,

a certifying step of certifying based the information relating to the route written on the radio tag acquired by the information acquiring step and the information relating to the regular route preset corresponding to the ID of the radio tag, and

a gate lock control step of locking the gate installed on the predetermined route if the certification is not permitted in the certifying section.

18. The certifying program according to claim 17, further comprising:

an NG flag writing step of writing the NG flag for inhibiting the use on the radio tag not permitted for the certification in the certifying step, wherein

the certifying step does not permit the certification for the radio tag with the NG flag written.
