Abstract

An apparatus and method for modifying RFID tag data in a portable terminal are provided. The method includes determining whether a UID of the RFID reader is received; when the UID of the RFID reader is received, determining whether RFID tag data corresponding to the received UID exists in an RFID data management database; and when the RFID tag data corresponding to the received UID data exists in the RFID data management database, recording the corresponding data in the RFID tag and transmitting the recorded data. The data recorded in the RFID tag can be dynamically modified according to the RFID readers that are located near the portable terminal and collect the RFID tag data.

Claims

1. A method for modifying an RFID (Radio Frequency Identification) data in a portable terminal using a controller, the method comprising the steps of:

determining whether a UID (Unique Identification) of an RFID reader is received;

determining whether RFID tag data corresponding to the received UID of the RFID reader exists in an RFID data management database; and

when the RFID tag data corresponding to the received UID data exists in the RFID data management database, recording the corresponding data in the RFID tag and transmitting the recorded data.

2. The method of claim 1, further comprising disabling a data transmitting function of the RFID tag when the RFID tag is activated.

3. The method of claim 1, further comprising requesting the RFID reader to send the UID to the portable terminal.

4. The method of claim 1, further comprising displaying a message indicating that it is impossible to generate the RFID tag data corresponding to the RFID reader, when no RFID tag data corresponding to the received UID exists in the RFID data management database.

5. The method of claim 1, wherein the RFID tag data management database includes the UID of the RFID reader and data allowing the RFID reader to operate.

6. The method of claim 1, wherein the RFID tag data management database is updateable by a user.

7. An apparatus for modifying an RFID (Radio Frequency Identification) tag data in a portable terminal, the apparatus comprising:

a database storing a plurality of RFID tag data corresponding to a plurality of RFID readers;

a controller for reading, from the database, an RFID tag data corresponding to a UID (Unique Identification) received from a specific RFID reader, and recording the read RFID tag data in an internal memory of an RFID tag; and

an RFID tag for transmitting the recorded RFID tag data to an RFID reader under control of the controller.

8. The apparatus of claim 7, further comprising a flag for enabling and disabling the data transmission function of the RFID tag.

9. A method for managing an RFID (Radio Frequency Identification) data in a portable terminal using a controller, the method comprising the steps of:

determining whether RFID tag data corresponding to received UID (Unique Identification) of an RFID exists in an RFID data management database; and

recording the corresponding data in an RFID tag and transmitting the recorded data if the RFID tag data corresponding to the received UID data exists in the RFID data management database.

10. The method of claim 9, further comprising disabling a data transmitting function of the RFID tag when the RFID tag is activated.

11. The method of claim 9, further comprising requesting the RFID reader to send the UID to the portable terminal.

12. The method of claim 9, further comprising displaying a message indicating that it is impossible to generate the RFID tag data corresponding to the RFID reader, when no RFID tag data corresponding to the received UID exists in the RFID data management database.

13. The method of claim 9, wherein the RFID tag data management database includes the UID of the RFID reader and data allowing the RFID reader to operate.

14. An apparatus for modifying an RFID (Radio Frequency Identification) tag data in a portable terminal, the apparatus comprising:

a database storing a plurality of RFID tag data corresponding to a plurality of RFID readers; and

a controller for reading, from the database, an RFID tag data corresponding to a UID (Unique Identification) received from a specific RFID reader, and recording the read RFID tag data in an internal memory of an RFID tag,

an RFID tag for transmitting the recorded RFID tag data to the RFID reader under control of the controller.

15. The apparatus of claim 14, further comprising a flag for enabling and disabling the data transmission function of the RFID tag.
