NFC (Near Field Communications) is a way for two devices to communicate very closely together, similar to short-range Bluetooth that does not require authentication. It is an extension of RFID, so anything you can do with RFID, you can do with NFC.
Since it can read and write tags, you can always use this for RFID tag projects only. We carry several different tags that work great with this chip. It can also work with any other NFC / RFID Type 1 to 4 tags.
The mini shield was designed by RF engineers using the best test equipment to create a layout and antenna with the highest possible range of 5 cm using 13.56MHz technology. You can easily attach the protective barrier to the back of the plastic plate using spacers and unreadable metals.
This shield is designed to use I2C or SPI communication protocols. SPI is the default, and it is also easy to change the protective shield to Show More
