How Arduino RFID Systems Work Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers.

Arduino library for MFRC522 and other RFID RC522 based modules. Read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader connected via ...

An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

Prices vary from USD 7 for clones, to USD 75 for "starter kits" (which might be a good choice if this is your first exposure to Arduino; check if such kit already includes the Arduino, Reader, and ...
