Imagine a ring that not only registers your credit cards, but also your bank account, health insurance card, driver’s license, keys and house keys.

Who’d have thought of that? It’s called the Ring and the idea is to use it as your ‘universal key’ for everyday needs, replacing your house keys, wallet, health insurance card and even your car keys.


If you’re not familiar with the concept, a smart ring can replace your wallet, house keys, and even your cellphone. However, this isn’t the only application of the smart ring.

It can also be used to store personal information, such as bank accounts, credit cards, passwords, and other sensitive data. This can prevent identity theft and prevent people from using your personal information to open new accounts without your permission.

Smart rings are the gadgets of the future. Easy to use and carry, it can include many functions. Researchers at the Fraunhofer Institute for Foundry, Composite and Machining Technology (IGCV) have conducted intensive research and developed a multifunctional smart ring. The ring is 3D printed and, as mentioned before, equipped with an RFID chip.


The transformation of hardware technology that enables the integration of electronic components into the manufacturing process is unique, said Maximilian Binder, senior researcher at Fraunhofer IGCV, in a statement.

This smart ring with an RFID chip is made layer by layer. A small part remains hollow, in which electronic circuits are integrated. The design is unique and modern, and the best thing about this ring is its versatility.

It can record data such as a user’s medical history, blood group information, or drug intolerance data, in case of emergency. It can also be used to open a smart door or pay at the supermarket checkout. The smart ring has many applications in the field of health and well-being, but also in daily life.


These gadgets are really useful for older people who may not be able to keep track of things or perform simple tasks without supervision. Let’s hope that more of these kinds of gadgets will appear, with even more advanced and better features. EDITORIAL RECOMMENDATIONS Oura Smart Ring Health Tracker for athletes
