The difference between RFID HID Mode and RFID MF7 Mode is that in RFID MF7 Mode | The difference between RFID HID Mode and RFID MF7 Mode is that in RFID MF7 Mode FMM125 understands RFID messages that are in hexadecimal text format and RFID HID Mode interpretes messages that are in binary format. The type of RFID message sent to FMM125 depends on the RFID reader. For example, RFID MF7 mode message looks like "$aa$02$03$04$17$89$00$01" while HID mode message is of following format: "1213141519". | ||
