Bilateral buyer-led transaction apparatus for sale and purchase of goods and services e.g. via internet has checking mechanism which makes purchase requests globally available to possible vendors

摘要

The apparatus allows future purchasers of goods and services to make a binding contract with potential vendors based on a purchase request. The apparatus includes a checking mechanism which contains the binding purchase requests of future purchasers. The checking mechanism makes the purchase requests globally available to possible vendors. Possible vendors then have the option to accept the purchase request and to conclude a contract with the corresponding purchaser. Typically, encryption techniques are used.
