You'd have to launch a server attack and access the POS files. I'm sure exploitDB had a few things posted a while back (if you're not familiar with metasploitvparrotOS,Kali, or Arch Linux then just stop here.). Honesty I've beenaking my own receipts and walking out with things for over a year and they don't really check them that well. Just make sure the UPC matches up and ur good. Also they won't work forr returns (unless you have a barcode/TC# that matches said items)
