THE 30STARTUPS OF KANSAI

Founded in 2018 and based in Osaka, Sinumy is a deep tech startup developing the world’s first fully hands-free authentication technology using Bluetooth. It holds patents for its two core technologies — high-speed, high-accuracy location measurement and settlement-level security — enabling authentication with zero operation and zero wait time. Simply walking through a gate completes authentication, and simply standing in front of a checkout completes payment, with no need to ever take a smartphone out of a pocket or bag.

Sinumy’s technology eliminates the need to tap or hold up a device at ticket gates, payment counters, and office access points. An estimated 250 million people with visual impairments and 75 million wheelchair users worldwide, and many more — stroller users and people whose hands are full with luggage — find this simple act difficult. Sinumy is guided by the curb-cut effect: improvements made for specific groups end up benefiting everyone. Just as curb cuts help wheelchair users, stroller users, and travelers alike, Sinumy aims to create a barrier-free society where everyone can pass through effortlessly, without thinking about authentication.

Sinumy’s uniqueness lies in using a single Bluetooth signal to perform location measurement and identity authentication at the same time. By receiving signals through multiple antennas, Sinumy cuts signal-strength fluctuation by roughly 30,000-fold, sharpening Bluetooth positioning accuracy from about 1.5 meters to 10 centimeters — enabling a high-speed, high-precision proximity-detection technology. A time-difference authentication method, based on the timing gap between signal transmission and reception, delivers fast, highly reliable identity verification even in crowded spaces while preventing spoofing. Together, these two patented technologies make possible a hands-free authentication experience, which has never been achieved anywhere in the world.
