ARDUINO NFC SHIELD

Availability: In stock

Only 100 left

Rs.1,600.00

Quick Overview

NFC (Near Field Communications) is a way for two devices very close to each other to communicate. Sort of like a very short range Bluetooth that doesn't require authentication. It is an extension of RFID, so anything you can do with RFID you can do with NFC. The Adafruit shield was designed by RF engineers using the best test equipment to create a layout and antenna with 10cm (4 inch) range, the maximum range possible using the 13.56MHz technology. You can easily attach the shield behind a plastic plate with standoffs and still read cards through a (non-metal) barrier. This shield is designed to use I2C or SPI communication protocols. I2C is the default, as it uses fewer pins: analog 4 and 5 are used for I2C (of course you can still connect other I2C devices to the bus). Digital #2 is used for "interrupt" notification.
