Each Jeweler will have their own approach, but let the Jeweler know the material is titanium and to add material to that. If you heat up the ring too much the epoxy will melt and the inlays will fail so be careful not to apply too much heat. It's usually a lot cheaper to just buy replacement rings.

A competent jeweler could remove some material in between the inlays I suppose :) I'd like to see pics of this if you do this.

RE #2 we have a team who work on custom rings. Unfortunately each ring is $10k+ as it requires management and hand crafting. See our Henry Holland rings as an example of this.

Custom NFC Ring

@GP97 Support will give you a new one for free. They ware well aware of the issue.

Where I work we have plastic printed passes with nfc chips in. When you assign the card to a person, you place it on a reader, read the tag number, then print it. I discovered my NFC ring can be added like any normal security card. So I can open the doors at work with a wave of my hand, although I still need to carry my pass for securtiy/compliance reasons, but it's a small piece of nerdy pleasure.

I am not sure because of I never used window phone.

I think you need to go back to the safe manufacturer to find out which chip it supports. You might even find it on the spec sheet of the product.
You need a sensor that will work with NTAG. In theory if it works with NTAG and is programable IE: accepts a scanned chip, then it should work. Perhaps find a shop that sell them and turn up with your ring, see if it reads it and can be programed to accept it.
There are lots of sensors and locks that are designed to work with MIFARE chips, which won't work with the NFC ring.
So just read up before you make a purchase.

@Maxime-C. Which ID length are you using? 4, 7 etc? There is also little and big endian?
@jasok2

I am looking at Rohos and hope to get a test result soon.

The payments ring (Java Card based?) I suspect will not be simply written to.

Here's my reply from support at the end of Febuary

"We're in the final stages of refining production of the payment-enabled NFC Ring (and associated back end systems) at the moment. We're currently aiming to begin dispatch in the next couple of months."

It'll be ready when it's ready

If your antenna + according circuit is matched at 13.56Mhz, there are no problem but I think it will be difficult to find an antenna that match with the according circuit currently on the keyduino and you will need to change some component value to improve your reading range ;)

@asher-moua said in Where is my order and tracking number?:

rder #8461 confirmed

I think that you should direct contact in the sales department. They can help you in a proper way.

Hello anyone ???

I'm looking to buy them for my wedding.guess I have to look for something else.

I have a Kerv payment ring and it works in exactly the same way with NFC readers. If the door lock could read your old ring, it will be able to read the payement ring with no issues.
I was enjoying unlocking my phone with my payment ring until Google disabled the feature in Oreo, boo.
