Business Method for Promoting Sales, Satisfying Customers with Little Cost

摘要

The detailed information about a product is made accessible to buyers. The information helps buyers or end users to properly use, maintain, and repair the product. For example, the information about an automobile in DVD disk can be played via a built-in automobile DVD player, showing users features of the automobile, how to operate the automobile etc. This is a big value add for satisfying buyers with little cost from manufacturers. Although no product is expected to work a long time even with proper operation and maintenance, buyers hope the product work as long as possible. If ever a problem happens, buyers need the information, to know and possibly fix the problem with minimum cost. Or, buyers identify the problem to be minor, and just continue using the product without repairing the product.
