Abstract

An RFID reader control system and method is provided. A protocol for controlling an RFID reader and an RFID reader control unit of a mobile phone is defined. Messages, information, commands, responses, and notification are constructed and transmitted between the RFID reader and the RFID reader control unit.

Claims

1. A method for disabling a tag device, the method performed by a processor and comprising:

transmitting, to a reading device, a reading command,

wherein the reading command allows the reading device to read all of a unique item identifier, a tag identifier and a user-defined memory of the tag device;

receiving, from the reading device, the reading response including a memory data;

transmitting, to the reading device, a killing command for disabling the tag device; and

receiving a killing response in response to the killing command,

wherein the killing command comprises a kill password and CRC-16,

wherein the reading device disables the tag device with the kill password, and

wherein the killing response includes information for authenticating the tag device when the killing command is performed successfully.

2. The method of claim 1, wherein the reading command includes a start address of the memory bank.

3. The method claim 1 wherein the reading command includes a code value identifying a type of the reading command.

4. A mobile terminal for disabling a tag device, the mobile terminal comprising:

an interface unit configured to transmit/receive data to/from a reading device; and

a processor configured to;

transmit, to the reading device, a reading command,

receive, from the reading device, the reading response including a memory data,

transmit, to the reading device, a killing command for disabling the tag device, and

receive a killing response in response to the killing command,

wherein the reading command allows the reading device to read all of a unique item identifier, a tag identifier and a user-defined memory of the tag device,

wherein the killing command comprises a kill password and CRC-16,

wherein the reading device disables the tag device with the kill password, and

wherein the killing response includes information for authenticating the tag device when the killing command is performed successfully.

5. The mobile terminal of claim 4, wherein the reading command includes a start address of the user memory bank area.

6. The mobile terminal of claim 4, wherein the command includes a code value identifying a type of the reading command.
