Problems solved by technology

[0003] At present, manufacturers of contactless smart card reader terminals usually match the antenna circuit through hardware matching, but mass production cannot control the offset of the resonance point caused by device errors in the circuit composed of resistance, inductance and capacitance. There is no way to reach the maximum test field strength when the contact smart card reader terminal reads the card, and there is a deviation of the card reading test field strength in the non-contact smart card reader terminal, which reduces the card reading performance of the non-contact smart card reader terminal and cannot be completed well card reader work

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a non-contact smart card reading terminal and a working method thereof. Background technique [0002] In the production of existing contactless smart card reader terminals, antenna matching is of great significance. Antenna matching means that the antenna resonates in a circuit composed of resistance, inductance and capacitance, that is, the virtual input impedance of a certain frequency range. The part is adjusted to 0 or near 0, so that the circuit presents pure impedance. At this time, the impedance modulus of the circuit is the smallest. The performance is the best, so detecting whether the antenna matches is a very important link in the production inspection of the performance of the contactless smart card reader terminal. [0003] At present, manufacturers of contactless smart card reader terminals usually match the antenna circuit through hardware matching, but mass pro...
