Abstract: An example system for device-independent point to multipoint communication 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 including 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. The system translates the message based on the destination user information and message endpoints and transmits the message to each endpoint of the message.

Abstract: A method of reconstructing a packet that includes financial card information from a mobile device uses a card reader. The card reader has a read head, a slot for swiping a magnetic stripe of a card and device electronics that includes a microcontroller with logic resources with code. The card reader has a unique identifier and associated cryptographic key. The same code is used to produce an encrypted and signed signal. The encrypted and signed signal, that includes the card reader identifier, is sent to the mobile device. The mobile device sends an encrypted and signed packet to a back end of a payment system. A cryptographic key is used to decrypt and verify the contents of the packet at the back end. Non-encrypted financial card information is sent to a payment gateway.

Abstract: A decoding system with a decoding engine running on a tablet. The decoding engine decodes signals produced from a read of a buyer's financial transaction card, accepts and initializes incoming signals from a read of a buyer's financial transaction card until the signals reach a steady state, detects the read of the buyer's financial transaction card once the incoming signals are in a steady stat, identifies peaks in the incoming signals and digitizes the identified peaks in the incoming signals into bits. A transaction engine runs on the tablet and is coupled to the decoding engine. A payment system is in communication with the transaction engine and with a buyer's financial transaction card institution or a first party's financial 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.
