Abstract
Methods and systems are provided for a universal key that enables a user to have access to any type of secured portal, both physical and electronic, in a wireless, hands-free, distance-independent manner without requiring contact or line of sight access between the key and the secured portal. The universal key is not distance-dependent, and each secured portal can be provided with its own prescribed activation range, if desired. Some portals may be provided with long range activation, such as 50 feet, while other portals may be provided with short range activation of a few feet or less. The type of portal being secured and the range of activation may be selected by the user and is not limited by the universal key. In addition, the universal key will provide access to the secured portals in a hands-free fashion so that the user need not push any buttons or take any other action in order to obtain access to the portal. The user need only carry the universal key somewhere on their person in order to access the portal.
