lol, fair enough. I found it too convenient to be able to do both things (the payment ring wouldn't start the car, so it had to be both).

Nice. I think you're going to end up wanting to have both of them the whole time though!

I wear multiple rings, so it's not such a big issue for me. A good thing to remember is if you can't do it with your NFC-enabled credit/debit card then you probably can't do it with the payment rings - it's the same system.

@Chris very cool, I did wonder with the comfort-fit shape but the slight seam suggesting all ceramic.

Nice!

Got a photo, jasok2? I won't get to see one of those up close unless I see one out in the wild. That might get weird and confusing.

Looks like the 'other' ring... got a decent photo of it? The ones from BankWest aren't that great.

@Pingi are you still using 19200 as the serial speed? If so, could you try some other settings there, up to 115200?

@Pingi that's definitely better than the last one!

Just to step back from everything and clear things a little, if you guys need to troubleshoot I'd recommend going via the elechouse manual from ~page 5. Once you've verified that it is hooked up correctly and is functioning with the example code then you have a known point to work forward from.

@three-west The ring is completely self-contained and doesn't require anything other than a contactless payment terminal to work its magic.
