In our work related to Connected Objects and the Internet of Things, we've built a few different devices capable of reading Near Field Communication (NFC) tags.
NFC is a Radio Frequency Identification (RFID) technology that allows two devices to exchange messages while in extremely close proximity.
We're developing new service experiences based on the ability to add inexpensive NFC tags to physical objects and recognize them when placed on or next to connected objects that are embedded with NFC readers.
For this, we've used a few different NFC readers that are compatible with Arduino micro-controllers.
Since all three boards use the PN532 NFC chip, they respond to the same command set and can read all common NFC tag formats. Depending on the application, each of these readers has it's advantage. For example, the Adafruit breakout board runs at 3.3v, making it ideal for use with the Arduino FIO.
The libraries available for each reader are largely similar, but not completely interchangeable. Additionally, the libraries don't easily support all the features we need, especially in regards encoding and decoding NDEF messages.
To simplify the process of switching between readers and tag formats, we created a single library that supports these three boards, I2C and SPI communication, and a variety of NDEF message formats written to Mifare Classic and Ultralight tags.
We've posted the library on Github in hopes that others will find it useful and help add features to it. If you are an Arduino developer working with NFC, have a look and let us know what you think in the comments below.
It's been thirteen years since we started Odopod.
We've always wanted one thing: to do the best work of our lives. Along the way, we have been joined by an eclectic and exceptionally talented bunch of people who wanted the same thing. Together, we've built a company we love.
Two years ago, Odopod was acquired by Nurun.
The acquisition was a validation of everything we had built. It was also a catalyst for some big changes we wanted to make. We began to tackle bigger, thornier problems and to work all over the world. With Nurun, we've had a series of huge wins and have been producing our best work yet.
That's why we recently decided to retire the Odopod brand, formally adopt Nurun as our name, and take the reins of Nurun's US operations.
We're all still here—same team with the same appetite for great work, only now with different e-mail addresses and more frequent flyer miles. And we're growing, so send your talented friends our way.
Keep an eye out for new work from Nurun. It will be our best yet.
