Abstract: A mobile computing device has processors, memory, voice communication circuitry, and communication circuitry configured to receive a request from a server for information to complete an information exchange. The computing device also has a display device configured to display at least one user interface window in response to receiving the request from the server. The user interface window includes a plurality of data entry fields corresponding to the request. The computing device has a proximity based communication circuitry configured to energize an external NFC device that is brought into proximity with the mobile computing device. When the external NFC device is energized, the computing device receives information from the external NFC device to populate at least one of the data entry fields. The communication circuitry is configured to submit data from the data entry fields to the server to facilitate the completion of the information exchange.

Abstract: At least one image, such as a QR code, taken by a camera of a mobile computing device is received. The at least one image includes an identifier of a location dependent good or service associate with the image. The location dependant service may be a service for using a parking space or charging an electric vehicle. The identifier is automatically extracted from the image, and a user is identified to pay for the good or service. The user may self identify himself by providing payment details, such as an account number, username, or login details, or the user may be automatically identified from his phone number, IP address, MAC address or any other unique user identifier. Thereafter, an account associated with the user, such as a debit or credit card account, is billed for the location dependent good or service associated with the extracted identifier.

Abstract: A request to authorize a payment transaction initiated on the client device is received by the system. In some embodiments, the request is received from a mobile client device connected to a cellular communications network. The request includes an IP address associated with a client device and a cellular phone number associated with the client device. The IP address is determined automatically without human intervention from the request. A cellular telephone carrier system associated with the cellular communications network is then queried using the cellular phone number associated with the client device. A response is received from the carrier system. The response includes the current IP address associated with the client device. The payment transaction is authorized when the IP address received from the carrier system matches the IP address received from the client device.

Abstract: A method and system to verify the identity of a user are described. The system may include a communications module to receive a billing telephone number and a private data segment associated with a user; an address detector to obtain a street address associated with the user; a private data processor to obtain one or more identification records, utilizing the obtained street address and the private data segment; and a matching module to compare the one or more identification records with the private data segment associated with the user to generate a match result.
