In simple terms, u disk is a memory card reader, but U disk because the chip is directly welded on the PCB board, plus a better brand makes good u disk reading speed is guaranteed, card reader plus storage card can be used as a U disk. u disk, full name USB flash drive, Eng

With the popularization of RFID applications, more and more software engineers need to use RFID reader programming to achieve their own needs. In order to make the software engineer understand the use of RFID reader faster, this paper chooses a commonly used USB drive-free RFID reader sdt-ha to do the analysis. USB-free drives typically use a USB HID interface be
