This JAKCOM R3F smart ring transforms how you interact with your phone by using NFC wireless frequency communication at 13.56MHz. It eliminates the need to reach for your device for routine tasks by enabling screen lock, app lock, and quick start functions directly from your finger. The ring also shares business cards, internet links, texts, and online files through a tap, making it useful for professionals and everyday users alike. With an original health module designed to improve human performance, the ring adds a wellness dimension to its practical utility. Its pure medical titanium construction ensures it can be worn continuously without irritation or discomfort.

Features and Construction

The JAKCOM R3F combines phone control, data sharing, and health monitoring in a single wearable device. Its construction focuses on durability and ease of use, with no charging required through its lifespan.

Material and Build

The ring is made from pure medical titanium, a material known for being lightweight, hypoallergenic, and resistant to corrosion. This makes it suitable for constant wear, even during activities involving water or temperature changes from -50 to +80 degrees Celsius. The design follows international popular elements, providing a simple and unobtrusive appearance.

Size and Practical Fit

Multiple model variants are available, including MJ02 and R3 series sizes from 7 to 12, as well as R3F sizes 7 to 12, allowing you to select a size that fits securely. The coverage range is 1.5cm, meaning the ring communicates only when close to a phone's NFC sensor, which helps prevent accidental activations.

Event or Professional Use
