How do you verify whether the detection function of the RFID Interaction Module is damaged?
Place an IC card close to the powered-on RFID Interaction Module mounted on the robot. The RFID Interaction Module is damaged if the light flashes incorrectly.
The RFID Interaction Module mounted on a robot cannot detect the IC card. If the IC card can be detected after the module is removed and replaced with another RFID Interaction Module, it can be determined that the removed module is damaged.
Remove the RFID Interaction Module from the robot and power it on. Place the IC card 100 mm directly above the "R" sign of the module. If the light cannot flash correctly when there is no external interference, the module is damaged.
