Abstract: Various embodiments of a system and method for personalized commands are described. The system and method for personalized commands may include a payment service including a command management component. Such payment service may be responsive to one or more base commands. The command management component may be configured to generate a user interface for specifying personalized commands that correspond to the base commands. The command management component may be configured to generate mapping information from the information received via the user interface. The command management component may be configured to receive one or more messages that may include commands for the payment service, including personalized commands. From the personalized commands, the command management component may be configured to determine a corresponding base commands (e.g., based on the mapping information). Once the base command is determined, the payment service may perform the base command.

Abstract: A transaction processing and authorization service. A transaction initiation message received from a source entity by the service may include one or more errors. The service may, in response to receiving an incorrect transaction initiation message, contact the source entity via a second communications channel and allow the source entity to correct the faulty transaction initiation message during the communication session. The service may allow the source entity to correct only incorrect or missing portions of the transaction initiation message, and thus the source entity may not be required to re-enter the entire message. Correction of the transaction initiation message may be performed as part of an authorization contact from the service to the source entity on a communications channel, and thus the correction may not require any extra communications attempts or sessions between the service and the source entity.

Abstract: Various embodiments of a system and method for message-based purchasing are described. The system and method for message-based purchasing may include a message-based purchase service configured to determine that a selection has been performed through a network-based interface. Such selection may be indicative of one or more items offered for sale via the network-based interface. The message-based purchase service may be configured to, in response to the selection of one or more items, send to a communication device, a message indicating a code corresponding to the selection. The message-based purchase service may receive from the communication device through a communication channel that does not include the network-based interface, a message including the code. The message-based purchase service may be configured to, in response to determining that the message received from the communication device includes the code, generate a purchase request for the one or more previously selected items.

Abstract: Embodiments of a system and method for receiving task requests from unregistered devices are described. Embodiments may include a communication interface service configured to receive from a communication device a message indicative of a request to perform a task. The communication interface service may determine that the communication device is not registered with an existing account that provides information for performing said task. The communication interface service may obtain identification and authentication information for an existing account via a communication channel. The existing account may be an account for that is accessible via a network-based interface. The communication channel through which the identification and authentication information is received by the communication interface service may be any communication channel that does not include the network-based interface of the existing account.

Abstract: System and method for authorizing transactions, such as payments or money transfers. A transaction authorization mechanism may be provided through which a transaction initiated via a first communications channel may be authorized through a second, separate communications channel or mechanism. A source entity may initiate a transaction to a target entity via a first communications channel to a transaction authorization service. The transaction authorization service may confirm the transaction with the source entity via a second communications channel. Various embodiments may use different communications channels, for example conventional telephone systems, mobile/cellular phone systems, and text messaging systems as the first or second communications channels. After the transaction has been authorized via the second communications channel, the transaction authorization service and/or the source entity may contact the target entity to inform the target entity of the transaction.

Abstract: System and method for authorizing transactions, such as payments or money transfers. A source entity may initiate a transaction with a target entity via a first communications channel. In initiating the transaction, the source entity may indicate that the transaction is to be performed through a transaction authorization service. The target entity may send a transaction initiation message to the transaction authorization service. In response to receiving the transaction initiation message, the service may authorize the transaction with the source entity via a second communications channel. To authorize the transaction, the source entity may provide a PIN number or other identifier via the second communications channel. After receiving and validating the response from the source entity, the transaction authorization service may inform the target entity that the transaction is authorized. The target entity may then complete the transaction with the transaction authorization service and the source entity.
