What sort of ring is it? If it's the silver titanium one then irritation would be rare as titanium is supposed to by hypoallergenic. Or is it the stealth bomber with the coating that may be causing irritation?

Thanks, looks good.

It occurs to me, as the delivery date is getting closer, that I don't remember seeing any pics of what is included in the collection pledge. I know, there's a description but I'm curious to see... Anyone have a picture or can point me in the direction of a missed update?

My elechouse reader (looks like the same red one Lokki has) came today, and I've just spent a couple of hours trying to get it to work.

Good news is it works with the supplied cards and arduino uno. I used the downloads from here

Literally just got it reading so still need to understand it more but those files are worth a try.

Can't try it with anything else though...

I don't know if this is any help, but I couldn't open the PDF from your link so went looking for the software elsewhere.

The files in this listing compile ok for me, still don't have one to check though...

Ok I think I'll get one of those at the end of the month. I know we're all pretty much guessing as to ring compatibility but hopefully it is.

What so we think of this one?

Seems to tick a few boxes but would it be compatible with the rings?

Does anyone have any advice as to compatible arduino NFC shields?
