It seem that the IoT (Internet of Things) is increasingly on people's minds these days, not least because -- as I mentioned in an earlier column -- it is estimated that there will be 50 billion entities on the IoT by 2020.
Near field communication (NFC) refers to a set of standards for small, handheld devices such as smartphones to establish radio communication between them by touching them together or bringing them into close proximity (usually no more than a few inches).
We're already seeing this sort of thing starting to appear, as in the ability to share photographs or exchange digital business cards by tapping smartphones or tablets together. This is just the tip of the iceberg compared to the myriad use models that are being discussed for the future. Before long, we'll be seeing this stuff in everything from fitness watches to washing machines and water meters.
For example, STMicroelectronics offers a family of M24SR dynamic NFC tags. At Embedded World 2014, ST will be unveiling and demonstrating its M24SR Discovery Kit, which contains everything you need to start adding NFC connectivity to any kind of electrical device.
In addition to the Discovery Kit itself, the M24SR development ecosystem also includes things like antenna reference designs, application notes, reference MCU drivers, and an NFC Android app.
If you happen to be attending Embedded World, take the time to visit ST at Hall 4-160, because the team will be handing out a limited number of free M24SR Discovery Kits. (Click here to pre-register for one of these kits, subject to availability.) Ooh, I so wish I was going to be there…
