NFC technology was derived from RFID and allows users to connect to other devices, make payments, send media and files, and use NFC tags, easily the most creative use case for the technology. You can create an NFC scanner app for practically anything, making NFC app development extremely popular.

NFC technology provides a simple method of contactless communication between gadgets in close proximity. An NFC tag can share and link to information including web pages, social media, customer loyalty platforms, and more.

You can also leverage NFC to open doors secured with contactless locks and log on to computers. All of these actions have something in common: they invoke an action based on you placing your phone (or any other NFC-enabled device) near the thing you want to interact with or read.

The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes of ROM and 1 Kbytes of RAM. The PN532 combines a modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy-to-use firmware for the different supported modes and the required host controller interfaces.
