Abstract

Disclosed are an RFID tag for an RFID service and an RFID service method thereof. The present invention includes a tag storage unit including a TID memory and a user memory; and a tag controller that inserts and stores a content name field including content name information related to an item attached with the corresponding tag in the user memory, wherein the tag controller inserts the content name information in a tag response signal according to the request of a peripheral RFID interrogator and transmits it or permits an access to the memory in which the content name field is inserted. The present invention includes and stores the content name information in the identification data stored in the RFID tag to allow a user to select only the desired tag when the interrogator simultaneously recognizes a plurality of tags and receive the desired contents through the network, making it possible to give convenience to a user and reduce time and the using fee of the network.

Claims

1. An RFID tag for an RFID service, comprising:

a tag storage unit including a TID memory and a user memory; and

a tag controller that inserts and stores a content name field including content name information related to an item attached with the corresponding tag in the user memory,

wherein the tag controller inserts the content name information in a tag response signal according to the request of a peripheral RFID interrogator and transmits it or permits an access to the memory in which the content name field is inserted.

2. The RFID tag for an RFID service according to claim 1, wherein the tag storage unit stores a unique item identifier (UII) as an item identification data for the item to which the corresponding RFID tags are attached.

3. The RFID tag for an RFID service according to claim 1, wherein the tag controller inserts and stores the content name field in a memory bank having a predefined address in the user memory.

4. The RFID tag for an RFID service according to claim 1, wherein the tag controller inserts the content name fields in the memory bank having any address in the user memory and stores the positional information of the memory bank, in which the content name field is inserted, in the TID memory.

5. The RFID tag for an RFID service according to claim 1, wherein the content name field includes a data field in which the content name data is stored and a data length field in which length information on the data field is stored.

6. The RFID tag for an RFID service according to claim 5, wherein the data field is continuously inserted in the back of the data length field.

7. The RFID tag for an RFID service according to claim 5, wherein the length of the data field is a character size of the content name data included in the data field and the character size is stored in a byte unit.

8. The RFID tag for an RFID service according to claim 7, wherein the character included in the data field is prepared in an ASCII CODE type.

9. The RFID tag for an RFID service according to claim 1, wherein the tag code memory includes a first memory bank in which a storage location is recorded, the storage location being inserted with the presence or absence of the corresponding content name field and a second memory bank that is continued to the first memory bank and is recorded with a start address of the content name field.

10. The RFID tag for an RFID service according to claim 1, wherein when the tag controller receives a first ACK instruction from the RFID interrogator, it transmits the address information of the user memory bank in which the content name field is inserted or the TID memory bank in which the positional information of the content name field is stored to the RFID interrogator.

11. The RFID tag for an RFID service according to claim 1, wherein when the tag controller receives a second ACK instruction from the RFID interrogator, it inserts and transmits the content name field including the content name data in the response signal.

12. The RFID tag for an RFID service according to claim 11, wherein the response signal includes an extended protocol control (XPC) field, wherein a content name indicator indicating whether there is the content name field is included in a predetermined field of the extended protocol control.

13. The RFID tag for an RFID service according to claim 11, wherein the content name field is inserted in the back of the UII included in the response signal.

14. An RFID service method of an RFID tag, comprising:

inserting and storing a content name field including content name information related to an item attached with the corresponding RFID tag in any one of a TID memory and a user memory;

after receiving a first ACK instruction from peripheral RFID interrogators, transmitting address information of a user memory bank in which the content name field is inserted or a TID memory bank in which the positional information of the content name field is inserted to the RFID interrogator according to a read instruction from the RFID interrogator; and

allowing to be accessed the RFID interrogator to the memory bank in which the content name field is inserted according to the request of the RFID interrogator.

15. The RFID service method of an RFID tag according to claim 14, wherein the storing includes inserting the content name data in the data field of the content name field and inserting the length information of the data field in the data length field.

16. The RFID service method of an RFID tag according to claim 14, further comprising extracting the item identification data (UII) from the EPC memory in which the item identification data (UII) is stored and inserting and transmitting it in the response signal to the first ACK instruction, when receiving the first ACK instruction from the RFID interrogator.

17. The RFID service method of an RFID tag according to claim 14, wherein the storing further includes inserting the content name field in the memory bank having any address in the user memory and storing the positional information of the memory bank, in which the content name field is inserted, in the TID memory.

18. The RFID service method of an RFID tag according to claim 14, wherein the storing inserts and stores the content name field in the memory bank having the predefined address in the user memory.

19. An RFID service method of an RFID tag, comprising:

inserting and storing a content name field including content name information related to an item attached with the corresponding RFID tag in any one of a TID memory and a user memory;

receiving a second ACK instruction from peripheral RFID interrogators;

extracting the item identification data (UII) and the content name information and inserting them in the response signal to the second ACK instruction; and

transmitting the response signal, in which the item identification data and the content name field information are inserted, to the RFID interrogator.

20. The RFID service method of an RFID tag according to claim 19, further comprising inserting the eXtended protocol control (XPC) field including the content name indicator indicating whether there is the content name field in the response signal.
