JAKCOM R4 Product Description
Marathon process Each ring needs to undergo forging for 2 days, sintering in a 1400 ¡É furnace for 5 days, thousand times of CNC polishing, coating and other post-procedures. It takes 35 days to present the ring in front of you.
New flagship of smart ring JAKCOM R4 is the fourth generation smart ring, it carries with multiple sets of RFID chip modules. And is capable of simulating four contactless RFID cards. Once again, it becomes a new flagship product.
Brand new design, brand new breakthrough The newly designed circuit structure has greatly reduced the electric field disturbance between the modules. Compared with the previous generation of products, it has increased the transmit-receive distance by three times, and can be easily compatible with a variety of card reading devices.
Multi-frequency bands and multi-standards From 125KHz to 13.56MHz, JAKCOM R4 can simulate encrypted IC cards or ID cards in a variety of formats, help you to effectively deal with all-fields card swiping scenes.
Independent of fixed phone or APP, safe, fast and login free, easy on the trigger of editing and sharing.
Information sharing JAKCOM R4 can share various cloud information, e.g., encrypted text, business card, web pages, network disk files.
