NFC is a popular wireless technology - we often hear from smart phone companies such as Samsung or HTC introducing their latest high-end phones supporting NFC. Near field communication (NFC) is a set of standards for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters.
For electronics geeks, we also want to use NFC technology to make our own things. This PN532 NFC RFID Module v3 is built around NXP PN532. The PN532 is very popular in NFC circles.
The IO pins of NXP532 are broken out on this module. If users want to use another interface such as UART or SPI, this module also makes it easy to connect those pins.
As basic function, this module reads and writes a RFID card. Various cards are supported.
Libraries for Arduino are available.
Two peer PN532 modules communicating with each other wirelessly.
Basic communication with Andriod Phones (NFC supported) is available.
