Adafruit customer Uberhound posted his awesome RFID project on the Adafruit forums.
Using Adafruit’s RFID and WAV shields, I’ve just finished installing a system to announce frequent visitors by their unique theme song.
For example, my arrival is announced by the theme song to Dr. Who.
Though the system requires visitors to have a Mifare card on them (their employer ID is usually fine), I’m hoping the new generation of NFC phones will work just as well.
We’ve taken our popular Adafruit PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC application. The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) 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!
