The more secure barcoding scheme is RFID. This problem revolves around barcodes just being a database reference, with no better way to tie the physical item to the database reference. Usually the weight of an item is in the database.
The current "modern" equivalent of swapping price labels is to buy expensive produce at the self-check, but to indicate you're purchasing low-cost produce.
