Microcontroller › 8051 › I have some problem regarding RFID madule interfacing….. › you will get RFID tag number
you will get RFID tag number as string of bytes from serial port.
so you have to first store all these bytes in a array
then just display all array characters one by one on LCD
for matching RFID tag you have to do same
make one array with same tag
now read RFID tag and store all characters in another array
compare elements of both array one by one.
