Computer program, method, and system for facilitating commercial transactions between a user and a vendor

摘要

Embodiments facilitate commercial transactions between a user and one or more vendors without requiring a user to provide information unique to a user account for the vendor. Embodiments prompt a user to select one or more vendors from a list of vendors. An authorization is obtained from the user to allow the computer program to retrieve the product from the list of vendors and on behalf of the user. The computer program then requests and receives, from each vendor, information for accessing an electronic resource of the vendor. In embodiments, the received information is unique to the user account for the vendor. The computer program then obtains the product from the vendor based on the received information. The computer program thus presents a centralized management service for obtaining product from a plurality of vendors and without requiring the user to provide user information unique to the user for each vendor.
