  • Patent number: 8352315
    Abstract: Systems, apparatus, and methods are provided for efficiently authorizing a transaction initiated by a consumer. An authorization can be generated before the consumer actually initiates the transaction. For example, a future transaction can be predicted, and an authorization can be generated for the predicted transaction. In this manner, the authorization can be ready and quickly used when the consumer does initiate the transaction. Previous transactions made by the consumer can be used to predict when the future transaction is likely. In various examples, the authorization can be sent to a specific merchant or to the consumer for use when the consumer initiates the predicted transaction, or saved by an authorization server for use in response to an authorization request from the merchant.

  • Publication number: 20130006847
    Abstract: 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 consumer's 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 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.
