US Patent 8121942 Systems and methods for secure and transparent cardless transactions

Systems, methods, and apparatus for handling and/or authorizing payment requests by a consumer for a transaction are provided. Payment information can be sent directly from a consumer to a non-merchant, thereby allowing no new entities to obtain the payment information. Transaction identifiers can be used to facilitate communications among the entities. The payment information can be sent to the non-merchant via a merchant application with a submit payment button directed to the non-merchant so little or no deviations from standard practices are required.
