The invention provides a device and a method for reading / writing a memory card in a radio frequency non-contact way. The device comprises a radio frequency transceiver module, a radio frequency modulation and demodulation module, a micro-control unit and a memory card interface module which are sequentially connected, wherein the radio frequency transceiver module receives a radio frequency signal of a memory card reading / writing request of a non-contact terminal, and matches the radio frequency signal of the memory card reading / writing request of the non-contact terminal into a first radio frequency signal; the radio frequency modulation and demodulation module modulates the first radio frequency signal into a first digital signal; and the micro-control unit converts the first digital signal into a memory card reading / writing command signal. The device and the method for reading / writing the memory card in the radio frequency non-contact way have the advantages of enabling the non-contact terminal to realize the reading / writing of various memory cards with radio frequency, meeting the requirements, on the reading / writing of the high-capacity memory cards with the radio frequency, of users, and providing convenience to the users, along with simple structure and convenient operation.
Description
technical field [0001] The invention relates to the technical field of radio frequency non-contact read-write memory card, in particular to a device and method for non-contact read-write memory card through radio frequency. Background technique [0002] With the continuous development of science and technology in modern society, the application of non-contact radio frequency card technology has gradually matured. There are many kinds of non-contact radio frequency cards that are common in people's daily life, such as non-contact IC bus cards, non-contact IC access control cards etc., but in the non-contact radio frequency card technology provided by the prior art: the storage capacity of its non-contact IC is too small, and the technology is not mature enough, which can not meet the requirement that people need to read and write large-capacity memory cards by radio frequency. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invent...
