Abstract

A method for distributing locating-relevant information includes providing a GPS position of a client to a server on a data network, and returning location-relevant information by the server based on the specified GPS position. Such location-relevant information include travel or tourist information (e.g., locations of tourist attractions, hotels, or restaurants). Commercial information such as discount coupons or advertising selected based on the Client's GPS position can also be provided. Financial or business transactions can be conducted using the GPS position for authentication or identification.
