A method includes receiving, by a network computing device of a multi-part code system, interaction information from one or more of a first and a second computing device regarding an interaction between the first and second computing devices. The method further includes generating a first and second portion of a code that are unusable individually. Alignment of the first and second portions of the code optically produces the code representative of the interaction information. A network application of the one or more of the first and second computing devices is operable to capture the optically produced code. The method further includes sending the first and second portions of the code to one or more of the first and second computing devices. When the optically produced code has been captured, the method further includes finalizing, by an interaction finalization module of the network computing device, the interaction.
