MIXED MODE TRANSACTION PROTOCOL

摘要

As opposed to using one type of technology from the beginning of a transaction to the end of a transaction at the point of sale, embodiments of the present invention are related to useful techniques for conducting mixed mode transactions. A mixed mode transaction combines at least two modes of communication used in transaction processing. A transaction may start by initiating the transaction using a first communication mode between a first device and a second device. The first device may be a consumers mobile device, and the device may be a merchant access device or point of sale terminal. To continue the transaction, a second mode of communication may be initiated. The second mode of communication may be dependent on the first mode or independent. The first and second modes of communication may operated simultaneously. The first and second communications modes may be a physical interaction-based mode, a contact or contactless chip mode, a Bluetooth mode, a WiFi mode, an infrared (IR) mode, or any other suitable communication mode.
