US Patent 11706034 Point-of-sale system and method

A point-of-sale (POS) system and a data analytic platform provides receipt modification. The POS system has a receipt monitor intercepting receipt data from a POS till. The receipt monitor modifies the receipt data to produce modified receipt data and the receipt monitor transmits the modified receipt data to a receipt printer. A data processing server may receive the receipt from the receipt monitor. The server structures the receipt data, extracts one or more attributes, and may provide modified receipt data to the receipt monitor.
