Hi, do you know how to write a code that can show the location of RFID reader? For example, if I scan the card on RFID reader in Malaysia, it will show "Location : Malaysia", if it in Indonesia, then it will show "Location : Indonesia". I want it to show the premise location where it was scanned in the Google sheets database. The hardware components that I use are Node Mcu and RFID Rc522
have a look at arduino-rfid-rc522-tutorial
