I just bought the Arduino NFC Module and it works great with the tag it came with but it doesn't recognize at all any of my NFC Whiztags, anyone knows how can I fix that?

Hi, maybe your tag is not compatible with our NFC module, or saying it doesn't support ISO 14443A/MIFARE or ISO 14443B, I didn't find any datasheet about Topaz 512 Chip which your tag uses.

NFC Module for Arduino

Introduction

This NFC Module for Arduino is discontinued now, you can choose its upgraded version Gravity: UART & I2C NFC Module as a suitable replacement.

Your credit cards: gone. Bus pass and train tickets: vanished.Welcome to Near Field Communications (NFC) Module for arduino, a contactless, Wi-Fi-lite style tech that could already be in your smartphone, and could soon be a regular feature of your commute.

Near Field Communications(NFC) is a set of short-range wireless technologies, typically requiring a distance of 10cm or less, for two devices such as smartphones or the similar things very close to each other to establish communication. Communication is also possible between a NFC device and unpowered NFC chips such as tags, stickers, key fobs and cards which do not require batteries.

The NFC Module for Arduino is designed to extend this powerful feature for your project or application based on Arduino.It integrates a PN532 NFC controller from Philips.The driver interface for this product is UART interface of the microcontroller. So it's possible for you to test it via a USB to UART converter directly. On the other hand, for the applications with microcontroller, the module provides an event for your processor when detects the NFC tags, stickers, key fobs, or cards via high speed serial uart.

I bought this to replicate a similar NFC module from a different supplier and was pleased to find that it used the same commands in Arduino. So I did not have to adjust my code too much. This is a neat module and found it easy enough to use. Only issues are the nature of NFC itself - you need to be quite close to read a chip. Uses could be to programme NFC for other devices or trigger an action in a connected device.
