WARRANTY RETENTION SYSTEM

摘要

This invention provides a central data repository and processing system where customers may access warranty information about products they have purchased from different vendors. Customers are given a membership card when they purchase a first warrantied product, and information is sent to the system at the time of each purchase. By connecting to the system over the internet, they obtain access to purchase receipts for each transaction, and warranty information for each product. The customer database can be mined by suppliers with a view to promoting the sale of accessories and extended warranties, or for creating demographic profiles for promoting the sale of other goods and services.
