I have developed a Arduino NFC Door Unlock Kit. Currently I'm storing the NFC UIDs into a SD card connected to a SD Breakout Board. But I want to store them in the EEPROM for reliability and cost effectiveness.
I've tried but failed to save and load from the EEPROM. Could anyone help with this issue.
