Abstract: The present disclosure includes, among other things, systems, methods and program products for delivering data over a computer network.

Abstract: Methods and apparatus, including computer systems and program products, for creating and using documents with machine-readable codes. A computer program displays a list of fields in an electronic document, receives user input selecting one or more of the fields, automatically generates generation instructions for a machine-readable code to be displayed in a final appearance of the electronic document, and stores the generation instructions in the electronic document. The generation instructions specify that the machine-readable code is to be produced using data to be provided for the selected fields. In some embodiments, the program can also evaluate the user input, as well as user modifications made to the electronic document, to determine whether the machine-readable code is validly configured. By guiding users through the process of setting up machine-readable codes, the program can help users create forms with machine-readable codes that have a high probability of being scanned and decoded successfully.

Abstract: Methods and apparatus, including computer systems and program products, for creating and using documents with machine-readable codes. A computer program receives user data provided for one or more fields in an electronic document, generates input data containing the user data and metadata that provides a self-contained description of the user data, encodes the input data into a machine-readable code, and generates a final representation of the electronic document with a display of the machine-readable code. Upon reading the machine-readable code, the metadata can be used to identify a set of fields in a target system to which to assign the user data. In some embodiments, the metadata and the user data can be transformed and sent to a target system. The use of metadata in this manner enables machine-readable codes to maintain a physical representation of data that facilitates transfer of the data back into an electronic environment.
