Scratch Resistant


Stress Tested

No Charging

No charging necessary

Unlike paying with your smart phone or smart watch, which typically run out of battery in a single day, the McLEAR ring never requires charging. So you can always keep it on your finger and never have to worry about it running low.

Risk Isolation

We created a new kind of computer, so we built an entirely new way to interact with your cards and accounts. The ring comes with a secure isolated bank account that sits between your cards and the store you make contactless purchases at. There is little chance of your card being taken, recorded or copied if it is on your finger.

Speed & Precision

Using your ring to pay is much faster than using a credit or debit card, or even taking out and unlocking your phone. It's always right there on your finger, ready to go.

Our accompanying RingPay app allows you to keep an eye on your spending, track expenses and pause or lock a lost or stolen ring in an instant - for extra peace of mind.

Eight Years of Engineering

Made from high-purity zirconia ceramic, the McLEAR Smart Ring is one of the strongest consumer electronic devices on the market. This makes it highly scratch resistant, so you do not need to worry about scuffing it. It is strenuously tested to withstand breaking throughout all normal day-to-day use – and is fully waterproof. The ring will not cause skin irritation thanks to it being designed with hypoallergenic properties.

Ring Sizing

Getting the correct size ring is important.
Once activated using the app, your ring can not be exchanged for a different size.

Here are a few pointers to help get it right...

20 Sizes available

Our rings come in a huge variety of sizes, from the dainty 4.5 all the way up to size 16 for those giants amongst us. You can be sure to find the perfect size without compromise, for a comfortable fit all day long.

All our rings are ‘Comfort Fit’ – which means that rather than being flat on the inside, they have a softened, curved inside edge to give the wearer a more comfortable fit for daily wear.

20 Sizes Available

Already know your size?

All our rings are sized in US-standard sizes. If you already know your ring size using a different metric standard (such as standard UK size, inside diameter etc) – we’ve created a handy ring size conversion tool to help you convert it easily.

Visit a Jeweller

Ring sizing can be very tricky to get right, especially if you have no idea what size you are to begin with. To ensure a perfect fit, we always recommend visiting a local jewellery store to have your finger sized.

This is the best way to ensure that you are going to get the perfect-sized ring, ensuring comfort all day long.
