Abstract: The present technology includes a point of sale system for facilitating interactions between a customer and a merchant in a payment transaction, and for communicating with a payment server to complete the transaction. The point of sale system includes a central processor, a payment object processor, a payment object reader interface, and a touch screen. The central processor is configured to execute an operating system and to execute a transaction engine configured to manage payment transaction specific functions of the point of sale system such as to control the touch screen to display payment transaction information on the touch screen, and to control the payment object processor to control the payment object reader to receive payment object information.

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. 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: A system is provided that includes a transaction engine running on a mobile device. In response to a financial transaction between a buyer and a seller, the transaction uses the mobile device to accept information selected including but not limited to information from financial transaction or information pertaining to financial transaction card used by the buyer in the transaction. At least a portion of this information is communicated with a third party financial institution or payment network to authorize the transaction. Encrypted information is sent to the third party payment system authorizing a financial transaction.

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 card reader device is provided that includes a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller. A read head is positioned in the housing. The read head reads data stored on the magnetic stripe and produces a signal indicative of data stored on the magnetic stripe. The read head has sufficient impedance to set amplitude of a signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted into a microphone input associated with a mobile device for providing the signal indicative of data stored on the magnetic stripe to the mobile device.

Abstract: A financial transaction card reader device includes a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller. A read head is in the housing, reads data stored on the magnetic stripe and for produces a signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted into a microphone input associated with a seller's mobile device for providing the signal indicative of data stored on the magnetic stripe to the mobile device. The signal is decoded in the mobile device.

Abstract: A card reader includes a read head in a housing. A jack is coupled to the housing and adapted to be inserted into a microphone input associated with a mobile device. An electronic system includes a card reader circuit, a communication system, a monitor system to manage card reader behavior between power cycles, a pathway system and a power subsystem that in operation receives a bias voltage from a mobile device.

Abstract: A decoding system, with a decoding engine, runs 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 until the signals reach a steady state, identifies peaks in the incoming signals and digitizes the identified peaks into bits. A transaction engine 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, and serves as an intermediary between the first party and a second party. The first party does not have to share his/her financial transaction card information with the second party. The transaction engine is configured to be coupled to a payment system and a first party's financial transaction card institution or a first party's financial account.
