Onion NFC-RFID Expansion
The new RFID & NFC expansion board for Onion! This board uses the PN532 controller chip, which is the most popular NFC chip, and is embedded in pretty much every phone or device that does NFC. It can read and write to tags and cards, communicate with phones (for example payment processing), and ‘act’ like an NFC tag. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use!
NFC (Near Field Communications) is a way for two devices very close to each other to communicate. It is an extension of RFID, so anything you can do with RFID you can do with NFC. You can do more things with NFC as well, such as communicate bi-directionally with cell phones. Because it can read and write tags, you can use this for RFID-tag projects.
