The Kerv Ring Brings Paying for Shopping Into the Future

Most of us have way too many pin, debit, and credit cards lying around and digging them out when it comes time to make a purchase can be a hassle, even if you only have one or two of each. The Kerv ring aims to simplify this process by moving your cards into a contactless payment capable ring that uses NFC (Near Field Communication) to transfer your card’s data to the card reader so that you can simply hold your hand near the card scanner, wait for the beep, and it’s done.

The ring costs £49.99, and is currently available for pre-order after a successful Indiegogo campaign. The ring is also fully working and ready for shipment, so it’s not something you wil be spending forever waiting on.

How Does It Work


Contactless payment options are increasingly popular because they allow you to quickly and easily make purchases of less than $25 without putting in your pin. Contactless payments are mostly popular in big cities, and have already been implemented everywhere from restaurants to Starbucks, which makes checking out a breeze, and even more so if you don’t have to reach for your wallet.

The Kerv ring allows you to add cards including metro, subway, and bus passes, bank cards, and other data directly onto their app or browser. You can also load the ring with cash to make payments so you don’t have to access your cards. Because the account also functions as an e-money account (Like PayPal) you can use this function to quickly and easily send money to friends and family.

Kerv also sells a prepaid card (UK only for now) available to allow you to reduce the risk of fraud by only keeping a prepaid debit card on your ring, so that you can make payments with your expendable cash (this is also a great function if you have a habit of spending too much). Kerv also has a fully secure and encrypted system to match the security of chip and pin cards, and has a system set up for handling lost and stolen rings.

Why Wouldn’t You Want This Ring?

For £49.99, you’re getting a ring that is basically equipped with NFC, something that your phone can already do. In fact, with Google Wallet, Apple Wallet, and other technologies, your mobile phone is going to be able to handle all of your cards and your payments, just like this ring, except in a device you already own. That’s a big downside to a technology that relies on convenience to be attractive. In fact, some contactless payment options already allow you to pay with your phone, which makes the Kerv basically redundant if you don’t mind adding this data to your phone. For example, Apple Wallet also allows you to set up notifications for when your cards are used, which can actually help you to reduce fraud and identity theft because you will immediately know when someone is using your card. You should also remember that contactless payment is only really catching on in urban areas, so if you’re not in a big city, it’s probably a waste of money.

Why Would You Want the Kerv Ring?

With the ability to put everything you need (including public transport cards) right on your finger, you can save hours fumbling for your wallet, purse, cards, or phone, and just breeze right through payment, ticketing, and other card verification areas. The Kerv uses the same technology in each of these cards, so it works with any cards, anywhere contactless support does (which is most public transport, work access cards, ticketing(not all ticketing, many still require barcode scanning), and other places.

At the end of the day, the Kerv ring is affordable, offers a lot of functionality, and a really great addition to the wearable smart jewelry field. It’s also one of the only options that isn’t entirely designed around Bluetooth functionality (no notifications here). If you don’t want to use your phone (or your cards) for payments, it can also be a really great investment.
