Because it can read and write tags, you can always just use this for RFID-tag projects. We carry a few different tags that work great with this chip. It can also work with any other NFC/RFID Type 1 thru 4 tag (and of course all the other NXP MiFare type tags)
The Duinofun 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.
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. This means you don't 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 any "classic" Arduino - NG, Diecimilla, Duemilanove, UNO
- as well as Mega R3 or later. For using the I2C interface with Mega R2
or earlier, two wires must be soldered as the I2C pins are in a
different location on earlier Megas.
Please note that there is a minor issue with the current version of the boards (v1.0). SEL0 and SEL1 are reversed on the silkscreen, so SEL0 is actually SEL1 and vice versa. This only affects users who wish to use UART or SPI to communicate with the PN532 instead of the default I2C, which is the communication bus supported by Duinofun's PN532/NFC library for Arduino. This will be update on the next version of the boards.
