Abstract

A unique ID generation apparatus that may generate a unique ID of a radio frequency (RE) card includes a card recognition unit that recognizes an RF card; a command transmission unit that transmits, to the recognized RF card, a plurality of commands which respectively correspond to a plurality of RF protocols; a response reception unit that receives, from the RF card, responses to one or more of the plurality of commands; and a unique ID generation unit that generates a unique ID of the RF card based on the received responses.

Claims

1. A unique ID generation apparatus that generates a unique ID of a radio frequency (RF) card, the apparatus comprising:

a card recognition unit configured to recognize an RF card;

a command transmission unit configured to transmit, to the recognized RF card, a plurality of commands which respectively correspond to a plurality of RF protocols, wherein the command transmission unit transmits a first command corresponding to a first RF protocol to the RF card, and a second command corresponding to a second RF protocol to the RF card;

a response reception unit configured to receive, from the RF card, a first response to the first command and a second response to the second command; and

a unique ID generation unit configured to generate a unique ID of the RF card based on a received response, wherein the unique ID generation unit generates an ID corresponding to the first RF protocol as the unique ID of the RF card, when the first response is received, and generates an ID corresponding to the second RF protocol as the unique ID of the RF card, when the second response is received.

2. The unique ID generation apparatus of claim 1,

wherein the first command includes a first type command and the second command includes a second type command, and

wherein the first response includes a response to the first type command and the second response includes a response to the second type command.

3. The unique ID generation apparatus of claim 2,

wherein the first type command includes a polling command, and the second type command includes a SELECT command.

4. The unique ID generation apparatus of claim 1,

wherein the first command includes a first polling command, and the second command includes a second polling command.

5. The unique ID generation apparatus of claim 4,

wherein the unique ID generation unit is further configured to determine a first part of the unique ID by using a response to one of the first polling command and the second polling command, determine a second part of the unique ID based on a response to a SELECT command, and generate the unique ID based on a combination of the determined first part and the determined second part.

6. The unique ID generation apparatus of claim 4,

wherein the first polling command is one or more of a REQA (REQuest A) command and a WUPA (Wake-UP A) command, and

the second polling command is one or more of a REQB (REQuest B) command and a WUPB (Wake-UP B) command.

7. The unique ID generation apparatus of claim 4,

wherein when the response reception unit is further configured to receive a response to the first polling command, and the command transmission unit is further configured to transmit a SELECT command to the RF card.

8. The unique ID generation apparatus of claim 1,

wherein the first command includes a REQA (REQuest A) command, and a WUPA (Wake-UP A) command, and the second command includes a REQB (REQuest B) command, a WUPB (Wake-UP B) command, and a polling command, and

wherein the command transmission unit is further configured to transmit a SELECT command to the RF card when the response reception unit receives a response to the REQA (REQuest A) command or a response to the WUPA (Wake-UP A) command.

9. The unique ID generation apparatus of claim 1,

wherein the response reception unit is further configured to receive an ID of the RF card, which is given in a process of manufacturing the recognized RF card, and

wherein the unique ID generation unit is further configured to generate the unique ID of the RF card based on the received responses and the received ID.

10. The unique ID generation apparatus of claim 1,

wherein the unique ID generation unit is further configured to generate a code by combining responses received by the response reception unit, the code including one or more numbers or characters as the unique ID that recognizes the RF card.

11. The unique ID generation apparatus of claim 10,

wherein the unique ID generation unit is further configured to encrypt the generated code.

12. The unique ID generation apparatus of claim 1,

wherein the unique ID generation unit is further configured to match the generated unique ID to the recognized RF card.

13. The unique ID generation apparatus of claim 1, further comprising:

a unique ID transmission unit configured to transmit the generated unique ID to a service providing server.

14. An identification information generating method of generating a unique ID of a radio frequency (RF) card, the method comprising:

recognizing an RF card;

transmitting, to the recognized RF card, a plurality of commands which respectively correspond to a plurality of RF protocols, wherein the plurality of the commands includes a first command corresponding to a first RF protocol, and a second command corresponding to a second RF protocol;

receiving, from the RF card, a first response to the first command and a second response to the second command; and

generating a unique ID of the RF card based on a received response, wherein the unique ID includes an ID corresponding to the first RF protocol as the unique ID of the RF card, when the first response is received, and an ID corresponding to the second RF protocol as the unique ID of the RF card, when the second response is received.

15. A unique ID generation apparatus that generates a unique ID of a radio frequency (RF) card, the apparatus comprising:

a card recognition unit configured to recognize an RF card;

a command transmission unit configured to transmit, to the recognized RF card, a plurality of commands which respectively correspond to a plurality of RF protocols, wherein the command transmission unit transmits a first command corresponding to a first RF protocol to the RF card, and a second command corresponding to a second RF protocol to the RF card;

a response information reception unit configured to receive, from the RF card, a first response to the first command and a second response to the second command;

a unique ID generation unit configured to generate a unique ID of the RF card based on a received response, wherein the unique ID generation unit generates an ID corresponding to the first RF protocol as the unique ID of the RF card, when the first response is received, and generates an ID corresponding to the second RF protocol as the unique ID of the RF card, when the second response is received; and

a service providing unit that executes a service process corresponding to the RF card based on the generated unique ID.
