Product Description

Feature:

The easiest to use RFID / NFC / PN532 Shield IC card expansion board can be used in Arduino!
Serial module radio frequency IC card sensor electronic building blocks
Easy to use, easy to connect, cost-effective serial RFID radio module. RFID radio frequency identification is a non-contact object recognition technology, it can automatically Identify the target through the RF signal and access to relevant data, so many interactive projects is to borrow this feature to achieve the identification of objects.
The perfect tool for any 13.56MHz RFID or NFC application.
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 to "interrupt" notification. This means you do not have to sit there and 'poll' the chip to ask if a target tag has been found, the pin will pull low when a card, phone, etc is within range. You Can adjust which pin is used if you need to keep digital # 2 for something else. It is also easy to change the shield over to SPI where you can use any 4 digital pins by shorting two solder jumpers on the top of the PCB. Compatible with the use of the I2C interface with Mega R2 or earlier, two wires must be soldered as the I2C pins are in a different location on earlier (2) with any "classic" Arduino – NG, Diecimilla, Duemilanove, UNO – as well as Mega R3 or later. 

Package includes:

1 x RFID RF expansion board
