Automated compatibility checking for hardware/software purchases at time of purchase

摘要

The present invention can include a pre-purchase method for determining computing item compatibility. In the method, configuration information associated with a computing system can be stored. A for-sale item to be used with the computing system can be detected. A compatibility between the for-sale item and the configuration information can be determined. A potential purchaser can be notified of results of the determining step before completing a purchase of the for-sale item. The method can be automatically performed by an online storefront system (e.g., a e-retailing Web site) or by in-store computing equipment, such as a cashier's register and/or an in-store kiosk.
