WHAT’S JAKCOM R4 SMART RING?
The Jakcom R4 is a multifunctional RFID smart ring and a successor to the R3 model. It can simulate contactless RFID cards such as your access card, membership card, parking card, and shopping card. You can also program the ring as a travel pass or a car key.
In addition, the ring’s NFC module enables it to serve as an extension to your mobile device by recognizing virtual calls and scene notifications. The Jakcom R4 can also share notes, business card details, and other cloud-based information.
Like the R3, this NFC smart ring is passive, which means it does not die or need charging any more. The Jakcom R4 is also IP68-rated, so it’s dust and waterproof.
The Jakcom R4 allows the user to trigger timed incoming calls on supported Android and iOS devices. Just make sure to get your ring near your device to start the call.
The ring can also quickly set off multiple preset notifications on supported Android and iOS devices. For instance, you can set emergency messages and instantly trigger it by inching your smart ring closer to your phone.
The Jakcom R4 allows you to store and share cloud information, including encrypted texts, electronic business cards, website pages, network disk files, and more.
