contactless payment ring and a tutorial on NFC antenna design

[ultratechie]

Hi,

I have a done a video about a contactless payment (NFC) ring that I have made. The video talks about NFC antenna coil design and how I used the concepts to make the wearable ring.

Here is a link to the video:



I am a hobbyist and I have started to make some videos about the projects I do. I would like to receive your feedback, especially on the quality of the video and the technical content.

Hope you like it.

Well done 

I have basic knowledge about how NFC works but I liked to see the data on the scope and your '3D' coil.
Looking at the data for the 2.2uH coil and the chip I guess you could have just soldered a 27p cap on the coil connections and be done, but for others the tuning demonstration on the SA can be an eye opener.
