NFC is a popular technology in recent years. We often heard this work while smart phone company such as Samsung or HTC introduces their latest high-end phones. Almost all the high-end phone in the market support 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.
The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It 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. If you want to do any sort of embedded NFC work, this is the chip you'll want to use!
This Module is base on PN532 Chip with 13.56MHz. It's is equipped with an onboard antenna, so no external antenna coil. The PN532 is also very flexible, you can use 3.3V TTL UART at any baud rate, I2C or SPI to communicate with it. You can easyly to develop NFC product with NFC library for Arduino.
