Overview: NFC has been a popular technology in recent years. We have heard this work many times while smartphone companies like Samsung or HTC are presenting their latest high-end phones. Almost all high-end phones on the market support NFC. Near Field Communication (NFC) is a set of standards for smartphones and similar devices to create radio communication by grouping them together or bringing them close, usually no more than a few centimeters. For electronics geeks, we also want to use NFC technology to make our own things. So we build this NFC RFID module. This module is built around NXP PN532. NXP PN532 is very popular in the NFC area. And the company offers a lot of technology documents for developers. We developed this module based on the official document. And to make things easier, we are also building a library for this module. We break out almost all of the NXP532 IO pins on this module. Users can easily connect and play. With our Arduino Sensor Shield, it's very easy to plug and play. However, if users want to use another interface like UART or SPI, these pins can also be easily connected. Description: Here we present three basic examples of this module. 1. Read / write RFID card As a basic function, this module could read and write RFID cards. Different cards can be supported. 2, P2P communication Two Peer PN532 modules could communicate with each other wirelessly. 3, NFC with Android phone. The basic communication stamp with Android Phone (NFC supported) has been completed. Currently we were able to set a URL on an Android smartphone and let it visit a website.
