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 of managing a result code, the method performed by a reading device and comprising:

receiving, from a mobile processor, a command for a specific operation;

determining whether or not the specific operation is performed, according to the command;

when the specific operation fails, storing a result code indicating a reason of the failure;

receiving, from the mobile processor, a result requesting command, wherein the result requesting command is used to get the stored result code, the stored result code indicating a last result code, and wherein the result requesting command includes a message type field, a code field and a payload length field, and does not include an argument field; and

transmitting, to the mobile processor, a response message in response to the received result requesting command, including last result code that was successful.

2. The method of claim 1, wherein the code field included in the result requesting command includes a code value discerning a type of a command.

3. The method of claim 2, wherein when the result requesting command is performed successfully, the response message further includes the code value included in the specific command.

4. The method of claim 2, further updating the result code based on a reason failure occurred by the received result requesting command, when the result requesting command failed.

5. The method of claim 1, wherein the result requesting command and the response message operate in pairs.

6. A reading device for managing a result code, the reading device comprising:

an interface unit configured to transmit/receive data to/from a mobile processor; and

a control unit configured to;

receive, from the mobile processor via the interface unit, a command for a specific operation,

determine whether or not the specific operation is performed, according to the command,

when the specific operation fails, store a result code indicating a reason of the failure, and

receive, from the mobile processor via the interface unit, a result requesting command,

wherein the result requesting command is used to get the stored result code, the stored result code indicating a last result code,

wherein the result requesting command includes a message type field, a code field and a payload length field, and does not include an argument field, and

wherein the response message includes the argument field, the argument field including a last result code that was successful.

7. The reading device of claim 6, wherein the code field included in the result requesting command includes a code value discerning a type of a command.

8. The reading device of claim 7, wherein when the result requesting command is performed successfully, the response message further includes the code value included in the specific command.

9. The reading device of claim 7, further updating the result code based on a reason failure occurred by the received result requesting command, when the result requesting command failed.

10. The reading device of claim 6, wherein the result requesting command and the response message operate in pairs.
