We've compiled some of the more frequently asked questions we've had from people when ordering an NFC Ring.

The ring

Q Is the Ring water-proof / water-resistant?

A We have tested our rings in a pressure chamber to an equivalent depth of 50m. You should be fine doing the dishes and taking a shower, however we urge caution with plunging into the Mariana Trench.

Q What type of material are the rings made out of?

A Our metal rings are made from a high quality nickel-free titanium. Our ceramic rings (the coloured rings) are made from a high-quality, scratch resistant advanced ceramic.

Q What is the storage capacity of each inlay in the ring?

A For the Titanium NFC Ring: 144 bytes, 1152 bits of awesomeness.
For the Ceramic NFC Ring: 888 bytes, 7104 bits of awesomeness.

Q What NFC tags are used inside the ring?

A In the Titanium NFC Ring we currently use the NXP NTAG203. In the Ceramic NFC Ring we currently use the NXP NTAG216.

Q I get tiny scratches on the titanium surface, is it easy for me to make my ring look as good as new?

A You can easily buff scratches out with a rag and some t-cut type polish.

Ordering, International Shipping and packaging

Q Do you ship internationally?

AHere on our USA-based store, we currently only ship within the USA, Canada or to Mexico. If you are outside of these locations, please visit our International store here:

Q What about duties and fees?

A Due to the complexity of international laws and taxes, we unfortunately can not include any duties or fees in our pricing structure. This means that you are responsible for any extra local fees incurred. If an order is refused, you are responsible for the original shipping expenses, as well as any additional duties, fees, customs or taxes incurred in shipping.

Q Will my order be trackable?

A All orders from our USA-based store are sent via USPS and are therefore tracked.

Q What will I get with my ring?

A Your ring comes in a specially designed custom ring box, with a leaflet with some information on how to get started and care for your ring, and some ’sweet spot’ stickers for your devices.

Interacting with third party devices

Q What other hardware devices can interact with the ring?

A Raspberry Pi and Arduino both have NFC modules available that work great with the ring.

Q What devices has this been tested on?

A We’ve tested on a number of devices such as the Samsung S3, S4, Nexus - please see our comprehensive listing of community tested devices. Our community over at the NFC Ring Forum are helping each other out by listing their devices. Check it out for further guidance.

Q What can the ring be used with?

A Any NFC enabled device. The possibilities are almost endless.

Q Can I use my ring for contactless payments?

A If you create your own method then yes but we don’t provide a mechanism to do this.

Q If I punch Chuck Norris will I destroy him utterly in the face?

A Only Chuck Norris can destroy Chuck Norris.

Q Which digital door locks work with the ring?

A All door locks with NFC(ISO14443) should work fine. We recommend the Samsung SHS-2421 as a good sub 100$ digital door lock that is easy to fit. Head over to our forum to get more information and discussions about NFC door locks.

Q Will the ring work with my iPhone

A The NFC Ring will only work with NFC enabled devices. Even the iPhone 6 (with NFC-based payment abilities) doesn't appear to support regular NFC interaction at the moment. If Apple release an iPhone with full NFC support then it should work fine. You can also use an NFC enabled case for your iPhone if you are desperate to get started.

Q Whats a sweet spot?

A The sweet spot is the place on your device where the ring is read most easily. Often this is right over the NFC antennae. Check this list of sweetspots for your device. We also provide a sweet spot sticker to help you locate this areA If your device is not listed this video will help you find it.

Q My ring isn’t recognized right away. What can I do?

A Try to roll your ring over the sweet spot of your device. It can take a little bit of practice to get used to using one of the Titanium NFC Rings, practice however does make perfect. The new Ceramic NFC Ring is generally much easier to use with more devices, due to the increased operating range.

Q What is the read distance?

A This varies by device and also ring model. For the Titanium rings, the best effect will generally be found within 1-2mm (effectively touching). The Ceramic NFC Ring models have a much larger operating range and can be read anywhere up to around 1-3cm, depending on the reading device.

Q Will this ring work with my phone if I have a case over it?

A A lot depends on the type of phone you have and how thick the exterior casing is. For best results it is recommended using a stick on protector, however some Titanium NFC Ring bearers have found good results with hard cases. With the Ceramic NFC Ring, you will not usually have any issues using your ring through a case, but it does depend on how strong the signal is from your device.

Q There are cheaper versions of this ring, why should I buy a genuine NFC Ring and not a copy?

A We had a conversation with one of the copies on our forum, we feel he explains by himself.


Q Is the NFC Ring unlock app included with the price?

A Yes.

Q What operating systems will be supported at Launch?

A There is an Android and Windows Phone 8 App, you can also use the ring with Blackberry, Android and there are modules for the Raspberry Pi. Unlock functionality is exclusive to Android

Q Is there a way to get only access to the NFC Ring unlock app?

A Not yet, however we hope in the future to have a free and open source version of this app available for everyone to use.

Q When will I receive the code to use the NFC Ring Unlock app?

A The activation code is accessible through the NFC Ring Control App. Simply Tap Register then follow the on-screen instructions

Q I have trouble with the NFC Ring apps. Where do I get help?

A Visit our forum at

Q Is there an unlock app for Windows Phone 8?

A No, due to limitations of Windows Phone 8 there is currently no such app.

Q Is there an app for iOS?

A There is currently no official app for iOS as iPhones and iPads are currently not NFC capable.

Q Why choose open source and what does it mean for the project?

A A ring should be both personal and community focused, because sharing is a big part of the core functionality we needed a way to easily support third party platforms and empower our community to create their own use cases and inventions, open source allows this.

Q Can I download the apps without going through that dastardly App Store?

A Yes! Android NFC Ring Control, Android NFC Ring Unlock

A We’re glad you like the ring as much as we do. Feel free to join our community on our forum.
