A multipurpose data exchanger

The invention relates to a multi-purpose data exchanger, comprising a housing, wherein the housing comprises a microprocessor, a USB splitter module, and a non-contact IC card reading and writing module, a contact IC card reading and writing module, a serial port module and an automatic burning and downloading device respectively connected with the microprocessor; The USB splitter module is connected with the automatic recording downloader. The microprocessor is used for centrally processing data inputted by a non-contact IC card reading and writing module, a contact IC card reading and writing module, a serial port module and an automatic burning downloader, and outputting the data to the corresponding module. The multi-purpose data exchanger can process various kinds of information technically and send the processed data back to the multi-purpose data exchanger for data interaction with the required related operations through a relay device, so that the user does not need to queue upat a counter or a busine
