Icare Technologies is an ajaccienne startup founded in 2016 by Jerémy Neyrou and Fabien Raiola. The system developed by ICARE consists of an intelligent ring equipped with NFC technology, which will allow it to replace all payment cards, car keys or homes, and current contactless identification devices. To ensure maximum safety, the ring is equipped with several patented systems: carrier recognition, instantaneous deactivation when removed, 256-bit AES encryption, control of wave emission... Thanks to these cumulative security, theft and fraud become almost impossible. Another challenge faced by the startup is to offer a fully autonomous ring with a photovoltaic charging system sufficient for its low consumption, and to allow unlimited use. The ring will be coupled with a smartphone app that will allow you to board and choose many uses.
