Arduino NFC Reader Chat Control

NFC readers are used for reading data from RFID cards. These cards are radio frequency ID cards which can send data without battery. Electricity is generated in the cards from the electromagnetic field of the NFC reader. The cards can be used for authenticating persons or object. You can control both RC522 and PN532 NFC readers. You can learn more about RFID cards and NFC readers on the internet.

You can chat with the device at the Ozeki 10 as the video shows below.
