Abstract

Device testing using radio-frequency identification (RFID) is described herein. The testing uses one or more RFID readers that interrogate an RFID tag on a mobile device and, in response to the interrogation, receive data from the RFID tag. The one or more RFID readers, in response to receipt of the data from the RFID tag, transmit a command to execute a test program on the mobile device. The results of the test program are then provided by the mobile device.

Claims

1. A method comprising:

interrogating, by one or more radio-frequency identification (RFID) readers, an RFID tag of a mobile device;

receiving, by the one or more RFID readers, data from the RFID tag responsive to the interrogating;

transmitting, by the one or more RFID readers in response to receiving the data from the RFID tag, a command to initiate a processing system of the mobile device to execute a test program stored in the mobile device; and

receiving results of the test program from the mobile device.

2. The method as recited in claim 1, the data from the RFID tag comprising a power-state indicator that indicates a power-on state or a power-off state of the mobile device.

3. The method as recited in claim 1, further comprising:

transmitting, by the one or more RFID readers, a command to power on the mobile device, the command to power on the mobile device being transmitted in response to the one or more RFID readers receiving the data from the RFID tag; and

transmitting, by the one or more RFID readers, a command to power off the mobile device, the command to power off the mobile device being transmitted in response to the one or more RFID readers receiving the results of the test program from the mobile device.

4. The method as recited in claim 1, wherein the one or more RFID readers includes a first RFID reader at a first physical location on an assembly line, a second RFID reader at a second physical location on the assembly line, and a third RFID reader at a third physical location on the assembly line.

5. The method as recited in claim 4, the first RFID reader transmitting the command to power on the mobile device, the second RFID reader transmitting the command to execute the test program, and the third RFID reader transmitting the command to power off the mobile device.

6. The method as recited in claim 1, wherein the receiving the results comprises receiving the results via a wireless transceiver that includes one of a Wi-Fi transceiver, a Bluetooth™

transceiver, a Near Field Communication (NFC) transceiver, or the one or more RFID readers.

7. The method as recited in claim 1, wherein the test program is stored in memory of the RFID tag of the mobile device and the test program includes executable instructions to enable or disable an antenna of the RFID tag of the mobile device.

8. The method as recited in claim 1, further comprising transmitting, by the one or more RFID readers, the test program to the RFID tag of the mobile device prior to the transmitting the command to execute the test program.

9. The method as recited in claim 1, further comprising:

transmitting, via the one or more RFID readers, a passcode and data to store in the RFID tag memory of the RFID tag in the mobile device, the RFID tag validating the passcode to allow or deny the data to be stored in the RFID tag memory, the data including executable instructions or information.

10. A mobile device, comprising:

a radio-frequency identification (RFID) tag configured to store data in memory of the RFID tag and communicate with an RFID reader, the data including executable instructions;

a processing system to interface with the RFID tag via a communication bus, the processing system being configured to;

receive a command from the RFID tag to initiate execution of a test program, the command being communicated to the processing system in response to the RFID tag receiving the command from the RFID reader;

execute the test program stored in the memory of the RFID tag; and

wirelessly transmit data generated from the test program to a computing device.

11. The mobile device as recited in claim 10, wherein the processing system is implemented to communicate a power-state indicator of a power-on state or a power-off state of the mobile device to the RFID tag to be stored in the RFID tag memory.

12. The mobile device as recited in claim 10, wherein the processing system is further configured to receive the test program from the RFID reader and store the test program in the memory of the RFID tag.

13. The mobile device as recited in claim 10, wherein the processing system is implemented to:

process a power-on command received from the RFID tag, the power-on command being communicated to the processing system in response to the RFID tag receiving the power-on command from the RFID reader; and

process a power-off command received from the RFID tag, the power-off command being communicated to the processing system in response to the RFID tag receiving the power-of command from the RFID reader.

14. The mobile device as recited in claim 13, wherein:

the processing system comprises an output signal line connected to a power management integrated circuit (PMIC) of the mobile device;

to process the power-on command is to toggle the output signal line to power on the mobile device; and

to process the power-off command is to toggle the output signal line to power off the mobile device.

15. The mobile device as recited in claim 10, wherein the processing system is implemented to transmit the data generated from the test program via a Wi-Fi transceiver, a Bluetooth™

transceiver, a Near Field Communication (NFC) transceiver, or the RFID tag.

16. A system comprising:

one or more radio-frequency identification (RFID) readers;

a mobile device including an RFID tag configured to communicate with the one or more RFID readers;

a computing device configured to communicate with the one or more RFID readers;

a test module that is executable in the computing device and configured to;

interrogate, via the one or more RFID readers, the RFID tag of the mobile device;

transmit, via the one or more RFID readers, a first command to power on the mobile device;

transmit, via the one or more RFID readers, a second command to initiate a processing system of the mobile device to execute a test program stored in the mobile device;

receive results of the test program from the mobile device; and

transmit, via the one or more RFID readers, a third command to power off the mobile device.

17. The system as recited in claim 16, wherein the test module is further configured to receive data from the RFID tag of the mobile device responsive to the interrogation of the RFID tag, and transmit the first command responsive to receipt of the data from the RFID tag.

18. The system as recited in claim 16, wherein the receiving the results comprises receiving the results via Wi-Fi wireless communication.

19. The system as recited in claim 16, wherein the test module is further configured to:

transmit, by the one or more RFID readers, a passcode and data to store in memory of the RFID tag of the mobile device, the data including a public key that is a shared key between a processor of the mobile device and the RFID tag of the mobile device; and

transmit, by the one or more RFID readers, a fourth command to lock the memory of the RFID tag of the mobile device effective to not allow write operations in the memory of the RFID tag.

20. The system as recited in claim 16, wherein the one or more RFID readers are further configured to transmit the test program to the RFID tag of the mobile device.
