McLEAR is a Smart Ring made for Contactless Payments at Points of Sale. It is based on NFC technology, and you can use it via an Android or iOS mobile app.
McLEAR Ring allows you to confirm payments with simple gestures. The ring can be connected to a credit card and bank account - however, only with certain UK providers, currently. The connection with the financial providers not only allows you to make secure contactless payments but also allows for keeping track of daily expenditure.
The system behind the McLEAR Smart Ring features a secure, isolated bank account that sits between the user's credit cards and the stores where contactless purchases are made. This setup reduces the risks of a credit card being stolen, recorded or copied - as the ring is mounted on your finger.
One of the benefits of NFC-enabled contactless payment rings - including McLEAR, is that you don't have to worry about running out of battery - the ring simply doesn't have one! When the ring is brought near the point of sale device, an electromagnetic induction field formed between the two. The needed energy is passed through the ring's NFC circuit to enable the required authentication procedure.
McLEAR ring is waterproof, scratch-resistant, and made of Zirconia - click for additional information.
