An Anonymous Transaction Service (ATS) solves or alleviates the problems outlined above. The ATS provides anonymous, automated, risk-based differential pricing that allows consumers to receive offers from multiple suppliers with only a single credit report. The ATS facilitates any offer between a supplier and consumer that first requires an evaluation of the risk associated with making the offer. The ATS can be used for any product or service, such as credit cards, home mortgages, automobile loans, appliance loans, debt consolidation loans, insurance products, advertising and dating services, to name only a few.
