Transformation of inputs including
beacon inputs,
Global Positioning System (GPS) inputs, captured
panorama inputs, user-penned descriptive inputs, and
payment-amount-specifying inputs, via components, into outputs including
user device POS configuration setting outputs and / or
payment-gateway-directed
authorization request outputs. Further, transformation of inputs including POS
scanner inputs, POS keyboard inputs, and / or POS printer-directed inputs, via components, into outputs including
compliance check outputs, tagged omnibus
record outputs, SKU-UPC mapping outputs, and / or convergence / correlation outputs. Additionally, transformation of inputs including older limited-capability POS
software image inputs and / or newer limited-capability POS
software image inputs, via components, into outputs including update directive outputs. Functionality set forth includes allowing user devices to directly communicate with
payment gateways, capturing and making use of
scanner-obtained data and printer-destined data in a way that does not require code alternation of already-installed POS
software, and allowing software of limited-capability POS devices to be updated without sending large, full-overwrite software images.
