Abstract
An electronic device includes a reader-writer unit configured to read from and write to an RFID tag and a control unit. The control unit is configured to control the reader-writer unit to read a tag ID or a tag data of the RFID tag and configured to prevent or warn against a multiple-writing if it is determined that the tag data of the RFID tag has been previously subjected to writing based on the tag ID or the tag data of the RFID tag read by the reader-writer unit.
Claims20
An electronic device, comprising:
- a reader-writer unit configured to read from and write to an RFID tag;
- and
- a control unit configured to control the reader-writer unit to read a tag ID or a tag data of the RFID tag and configured to prevent or warn against a multiple-writing if it is determined that the tag data of the RFID tag has been previously subjected to writing based on the tag ID or the tag data of the RFID tag read by the reader-writer unit.
A method for controlling an electronic device having a reader-writer unit configured to read from and write to an RFID tag, comprising:
- reading, by the reader-writer unit, a tag ID or a tag data of an RFID tag;
- determining whether the tag data of the RFID tag has been previously subjected to writing based on the tag ID or the tag data of the RFID;
- and
- if it is determined that the tag data of the RFID tag has been previously subjected to writing, preventing writing of the tag data to the RFID tag or warning against a multiple-writing.
A method for controlling an electronic device, having a reader-writer unit configured to read from and write to an RFID tag, comprising:
- reading, by the reader-writer unit, a tag information from an RFID tag;
- determining whether the RFID tag has been previously written based on the tag information of the RFID;
- and
- if it is determined that the RFID tag has been previously written, providing a warning of previous writing to the RFID tag.
