Ordered according to the instructions of the seller. You need to wrap the rope around your finger, then measure it with a ruler and choose the table. Only 6 sizes and two colors: black or white.

Send me the package in about 3 weeks with Ali from China. Track to track, to the seller to apply separately was not necessary.

The packaging was very cool and such a shame not even to give an original gift. Unfortunately, I already threw it away, because they do not keep in the house package, but you can see in the video below.

The application is very light, weighs only a few megabytes.


Come to the most important. Actually, why do you need this ring?

  • Automatic unlocking of the smartphone or tablet. Just take it in your hand and he rasplachivaetsya automatically;
  • Special moves can launch the desired application (it is programmed in advance);
  • Also depends on what kind of party to hold the finger with the ring, add new functions;
  • Well, you can use it with any device that supports NFC. For example, the castle at the intercom, smart home, contactless payments in stores. But the problem is that few places even in the capital to support these modes.


Smart ring Jakcom R3 is very light and looks even and easy, but attracting people’s attention — I checked myself.

Created from some kind of alloy on their website you can read the process of making something very steep and tricky, so I will not do.

It is very important to me: working at all without any power. When hold the device, whether a magnetic door lock or smartphone, its chip is powered by it’s magnetic field and then gives feedback.

Again, took on Aliexpress here.
