Abstract: A just in time personal information sharing system employs short-range wireless communication to detect the presence of a user and identify them prior to sharing the user's information. The user stores personally identifying information within their user device and controls which parties it may be shared with. Subsequently when a user is detected within a location using a wireless terminal, the user's presence is verified using a biometric profile, and if confirmed, then the user's personally identifying information is shared with the other transacting party for temporary use in completing a desired transaction. In this manner, no transacting party is required to maintain user information, and in addition, a user controls their own information and its sharing without the need for arduous user input to facilitate the same.
