3db Access

3db Access (3db) provides solutions to the problem of securing applications and systems relying on proximity verification. Proximity verification determines how close two wireless devices are from each other in terms of physical distance. It is currently used by several systems to provide access to vehicles, buildings, and mobile payments in a insecure way. 3db's novel technology will enable secure proximity verification while keeping the convenience and high usability of the current (insecure) systems.
