Olivia, Thanks for the kind thoughts and motivation. Please press the heart on this idea if you like it. Fresh Lids does indeed support barcodes on containers and it is not necessary to paste a label on those items that already have barcodes. Please see the presentation video above so you can see how it works. Fresh Lids connects to a back end database with millions of products. You can even add items to this product DB if it does not find it , so you can find it next time you scan it, or if other people scan it.
