Point of sale intermediation system

Abstract

A point of sale intermediation system is adapted to be integrated with a point of sales terminal, scanning device, receipt printer and/or additional peripheral devices. The system includes a first intermediary device that receives the electronic barcode scanned text data output from the scanning device and relays it to a data manager that utilizes the data represented in the electronic barcode scanned 10 text data output and relays an electronic modified barcode scanned text data output back to the first intermediary device, which then relays the electronic modified barcode scanned text data output to the terminal. A second intermediary device that device receives an electronic printer data output from the terminal and relays it to the third-party data manager. The third-party data manager utilizes the data represented in the electronic printer data output and relays an electronic modified printer data 15 output back to the second intermediary device, which then relays it to the printer
