Embodiment 1
[0042] see figure 1 , which is a structural schematic diagram of the device for commissioning and testing the communication distance of the radio frequency SIM card swiping card provided in the first embodiment, the device 100 includes a main controller 101, a radio frequency transceiver circuit 102, a radio frequency antenna 103, a display module 104, a key circuit 105, and a power supply circuit 106 .
[0043] The RF transceiver circuit 102 is bidirectionally connected to the main controller 101 , and the RF transceiver circuit 102 is electrically connected to the RF antenna 103 . On the one hand, the main controller 101 processes the data command through the radio frequency transceiver circuit 102 and transmits it through the radio frequency antenna 103; on the other hand, the radio frequency transceiver circuit 102 and the radio frequency antenna 103 can realize wireless communication with the peripheral radio frequency SIM card.

Embodiment 2
[0051] see image 3 , a flow chart of a method for commissioning a radio frequency SIM card swiping communication distance provided in Embodiment 2, which includes the following steps:
[0052] Step a1, preset detection orientation and distance:
[0053] The device 100 is placed directly behind the terminal provided with the radio frequency SIM card 200, and the distance between the two is equivalent to the actual required communication distance between the radio frequency SIM card and the radio frequency card reader. In practice, since different card swiping environments have different requirements for distance, if the card reading distance between the radio frequency SIM card and the radio frequency card reader is required to be close, the distance between the device 100 and the radio frequency SIM card 200 is also relatively close; The distance between 100 and radio frequency SIM card 200 is far;
[0054] Step a2, set the RF signal strength threshold:
[0055] The receiv...
Embodiment 3
[0066] see Figure 4 The device 300 for commissioning the communication distance of a radio frequency card reader provided in Embodiment 3 has the same structure as the device 100 provided in Embodiment 1, and will not be described here again.
[0067] see Figure 5 , is a structural schematic diagram of the radio frequency card reader provided in the third embodiment. The radio frequency card reader 400 includes a display module 401 , a button circuit 402 , a power supply circuit 403 , a CPU 404 , a radio frequency transceiver circuit 405 , a radio frequency antenna 406 , a storage circuit 407 , a communication circuit 408 and a communication interface 409 connected to the communication circuit 408 . The display module 401 , button circuit 402 , radio frequency transceiver circuit 405 , storage circuit 407 , and communication circuit 408 are respectively electrically connected to the CPU 404 and controlled by the CPU 404 . The radio frequency antenna 406 is connected to the ...
