What is an NFC ring?

The appearance of such an accessory resembles an ordinary jewelry, but there is one exception – an embedded chip that provides connection with other devices. The first prototype of such a product was a project called NFC Ring, launched and funded by the KickStarter crowdfunding platform. In 2013, the creators of the “smart” ring managed to collect the necessary amount, which made it possible to realize the original plan.

The designs of modern NFC rings are not particularly original and have a classic design. Sometimes there are quite curious samples with specific colors and patterns on the body. The size of the accessory may vary depending on the thickness of the finger (usually 57-70 mm), and the total weight is about 23 grams.

Rings are usually made of a special alloy of ceramic and tungsten, which guarantees high strength and resistance to damage. In addition, such products have advanced dust and moisture protection according to the special IP62 standard.

Today, when Chinese companies have begun to develop NFC rings, a considerable number of worthy and inexpensive (10-15 dollars) alternatives have appeared on the market. An example of such a product is Jakcom Smart Ring R3F, which allows you to use many useful features of a smartphone without its direct participation. At the moment, these include unlocking the device, paying for purchases, as well as interacting with smart home components.

Thus, it works with bank terminals in stores that support wireless payment for goods, as well as unlocking doors that have an NFC key. Thanks to a special application, the accessory can be configured to perform various tasks, such as turning on the camera or entering sleep mode.
