Accessories/ NFC Smart Ring

NFC Smart Ring wearable with customizable actions and support for iOS, Android and Windows. Made of stainless steel, the NFC Smart Ring is an electronic wearable that connects to your mobile devices through near field communication (NFC), allowing you to replace access cards, create automation shortcuts, and even store small data.

You can use the NFC Smart Ring for a myriad of applications such as unlocking your phone or doors, sharing digital business cards (and other data), launching mobile apps, triggering home automation shortcuts, and even as a replacement for contactless cards, access control cards, etc.

Basically, the NFC Smart Ring can do anything that a traditional NFC card does, but in a wearable and smaller form factor.

It can be configured with any mobile device, computer or tablet that has a NFC sensor, including iPhone XS/XR (iOS13) and above, Android and Windows.

To check whether your smartphone or tablet has NFC compatibility, go to your system settings. If your device is NFC ready, simply turn on the NFC feature and download apps like NFC Tools Pro so you can manage and customize what your ring does.

Fully waterproof, it does not require any power source or charging. The built-in NFC chip holds power and stores data for years.

A perfect gift for geeks and tech enthusiasts, this ring is available in diameters sizes to perfectly fit your finger. See the size chart below to find the correct size for you.

Popular Questions

Unfortunately we cannot offer support or guidance on how to set up and use electronic products or apps. You must have NFC knowledge and understand how NFC apps work. The manufacturer recommends apps like NFC Tools Pro but you may search for other apps you like more.

The NFC Smart Ring works with any NFC reader built in vending machines, access points, computers, tablets and smartphones including Android, iPhone XS/XR (iOS13) and above.

The ring's NFC antenna (black dot) must be pointed at the same direction and aligned to/facing the NFC reader on the back of your mobile phone or where the NFC sensor is located.

NFC technology is highly directional. The form factor of NFC cards enables large antennas in flat areas, whereas a NFC ring comes with a much smaller antenna in a round shape, requiring you to position and align it much more carefully than you would with a flat and large card.
