Abstract: Methods and systems of collating and transmitting information relating to a payment transaction are provided. Current location of the mobile device is determined and merchant data, concerning merchants located within a predetermined distance of the current location of the mobile device is obtained. A list of merchants is generated based on the merchant data and presented on the mobile device. The user is requested to select a merchant from the list of merchants and input data in relation to the payment transaction through the user interface of the mobile electronic device, which requires the input data to be in a predetermined format. The mobile device generates a transaction report, based on the input data and merchant data associated with the merchant selected by the user, in a format compliant with requirements of a backend server and then transmits the transaction report towards the backend server for automatic processing.
