Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for transferring money using email. One of the methods includes receiving, at a user device, user input of a request to transfer a payment amount from a recipient account with a payment service system to a sender account of a sender with the payment service system. A draft email message is generated, the message having content identifying the requested payment amount, the draft email message including a confirmation link to a network resource associated with the payment service system, wherein upon receiving an indication that the recipient selected the confirmation link, the payment service system identifies a sender account of the sender and a recipient account of the recipient and initiates a transfer of the requested payment amount from the recipient account to the sender account.

Abstract: A payment transaction between a passenger and a driver may be processed using a mobile device of the passenger and a mobile device of the driver. For example, the mobile device of the passenger and the mobile device of the driver may be associated for processing the payment transaction. Fare data for a ride that is offered by the driver may be received from the mobile device that is associated with the driver and payment data for the passenger may be received from the mobile device that is associated with the passenger. A payment processing server may cause the payment transaction to be processed.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for sending or requesting money to or from multiple recipients using email. One of the methods includes receiving, at a user device, user input from a sender of a request to send a respective payment amount from a sender account of the sender with a payment service system to multiple recipient accounts of the payment service system. User input indicating respective recipient email addresses for the multiple recipients is received. A draft email message is generated, the draft email message being addressed to each of the multiple recipients, the draft email message including respective recipient email addresses for each of the multiple recipients. An indication that the sender sent the email message to the multiple recipients is sent to a payment service system.

Abstract: A decoding system has a decoding engine running on a mobile device. The decoding engine decodes signals produced from a read of a first party's financial transaction card. The decoding engine accepts and initializes incoming signals from a read of the first party's financial transaction card. A transaction engine runs on the mobile device and is coupled to the decoding engine. The transaction engine receives as its input decoded first party's financial transaction card information from the decoding engine. At least a portion of a first party's financial card information or information relative to a first party's financial account is used to create a mobile device payment application on the mobile device.

Abstract: A system (and method) for device-independent point to multipoint communication is disclosed. The system is configured to receive a message addressed to one or more destination users, the message type being, for example, Short Message Service (SMS), Instant Messaging (IM), E-mail, web form input, or Application Program Interface (API) function call. The system also is configured to determine information about the destination users, the information comprising preferred devices and interfaces for receiving messages, the information further comprising message receiving preferences. The system applies rules to the message based on destination user information to determine the message endpoints, the message endpoints being, for example, Short Message Service (SMS), Instant Messaging (IM), E-mail, web page output, or Application Program Interface (API) function call.

Abstract: A system is provided that includes a transaction engine running on a mobile device.

Encrypted information is sent to the third party payment system authorizing a financial transaction.

Abstract: A new approach is proposed that contemplates systems and methods to enable an individual to complete a financial transaction by swiping a magnetic stripe card through a card reader connected to a mobile device. The size of the card reader is miniaturized to be portable for connection with the mobile device. The card reader is configured to reliably read data encoded in a magnetic strip of the card with minimum error in a single swipe and provide a signal that corresponds to the data read to the mobile device, which then decodes the incoming signal from the card reader and acts as a point-of-sale device to complete the financial transaction. Such an approach enables a person to become either a micro-merchant (payee) or a buyer/customer (payer) without having to purchase expensive card reader devices or software.
