- The mini NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC.
- This chipset is very powerful, and can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag.
- While the controller has many capabilities, our Arduino library currently only supports reading/writing tags, and does not support phone-to-shield communication, tag emulation (which requires an external ‘secure element’ only available from NXP) or other more advanced features at this time.
- 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.
- 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 mini shield was designed by RF engineers using the best test equipment to create a layout and antenna with 5cm 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.
- SPI is the default, 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.
- Small dimension and easy to embed into your project
- Support I2C, SPI and HSU (High Speed UART), easy to change between those modes
- Support RFID reading and writing, P2P communication with peers, NFC with Android phone
- RFID reader/writer supports:
- Mifare 1k, 4k, Ultralight, and DesFire cards
- ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX)
- Innovision Jewel cards such as IRT5001 card FeliCa cards such as RCS_860 and RCS_854
