1. A method of operating a reading device, the method performed by the reading device and comprising:
- receiving, from a mobile processor, a start test mode command including a first message that instructs the reading device to enter a test mode,wherein a data field of the first message being communicated between the mobile processor and the reading device is processed according to a reading device processor interface protocol, andwherein the test mode is used for performing a test certification including a receive sensitivity test of the reading device;
entering into the test mode according to the start test mode command;
receiving, from a tag device, a second message according to an A/I protocol in the test mode;
performing a generating operation of a test mode message, the test mode message including a type field and a data field in the test mode,wherein the generating operation includes,inserting the received second message according to the A/I protocol itself into the data field, and inserting a value indicating the test mode into the type field; and
transmitting, to the mobile processor, the generated test mode message for the test certification including the receive sensitivity test of the reading device,wherein the receive sensitivity test is performed by receiving an A/I packet and the reading device is configured to accumulatively add a number of successfully received bits, in the test mode.

6. A reading device, comprising:
-
a reading device-processor interface unit configured to transmit/receive data to/from a mobile processor; an air interface (A/I) unit configured to transmit/receive data to/from a tag device; and a control unit configured to; receive, via the reading device-processor interface unit, a start test mode command including a first message instructing entering into a test mode, wherein a data field of the first message being communicated between the mobile processor and the reading device is processed according to a reading device-processor interface protocol, and wherein the test mode is used for performing a test certification including a receive sensitivity of the reading device; enter into the test mode according to the start test mode command; receive, from the tag device via the A/I interface unit, a second message according to an A/I protocol in the test mode; perform a generating operation of a test mode message, the test mode message including a type field and a data field in the test mode, wherein the generating operation includes, inserting the received second message according to the A/I protocol packet itself into the data field, and inserting a value indicating the test mode into the type field; and transmit to the mobile processor via the first interface unit, the generated test mode message for the test certification including the receive sensitivity of the reading device, wherein the receive sensitivity test is performed by receiving an A/I packet and the reading device is configured to accumulatively add a number of successfully received bits, in the test mode. - View Dependent Claims (7, 8, 9, 10, 13, 14)
