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: A method of providing validation data associated with a subscriber line of a telecommunication network. The method includes obtaining line data of the subscriber line wherein the line data is suitable for interrogating a line identification database (LIDB). The method interrogates the LIDB with the line data to obtain reference subscriber data associated with the line data, and processes the reference subscriber data to obtain validation data associated with the subscriber line. The invention extends to a subscriber line validation system to validate a subscriber line of a communication network.

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 is described of providing validation data associated with a subscriber line of a telecommunication network using a validation system. The method includes obtaining line data of the subscriber line wherein the line data is suitable for interrogating a line identification database (LIDB). The method interrogates the LIDB with the line data to obtain reference subscriber data associated with the line data, and processes the reference subscriber data to obtain validation data associated with the subscriber line. The method includes identifying a local exchange carrier (LEC) associated with the subscriber line to determine if a billing arrangement exists between the validation system and the LEC. The invention extends to a subscriber line validation system to validate a subscriber line of a communication network.

Abstract: A method is described to verify the identity of a user. The method, in one example embodiment, comprises obtaining automatic number identification (ANI) data or billing telephone number (BTN) data associated with a subscriber line of a telecommunications network; obtaining identification data associated with a subscriber, said identification data being different from the ANI data or the BTN data; searching a first database using the ANI data or the BTN data to determine first reference subscriber data; searching a second database using the identification data to determine second reference subscriber data; comparing the first reference subscriber data to the second reference subscriber data; and verifying an identity of the subscriber based on the comparing.

Abstract: A method to validate a payment method for a sale via the Internet includes communicating selection data to a remote user terminal wherein the selection data provides the user with an option to select an ANI capture mechanism. The ANI capture method may include one or more of receiving a user-initiated communication, and initiating a communication with a telephone line number associated with a valid billing telephone number. The invention extends to transaction processing system and to merchant network equipment and transaction processing equipment.
