Scan UPC and display custom metafield on screen

[CandyQueen]

Hello. I'm looking for something that sounds basic but unfortunately I don't think anything like this exist. I need an app that scans the barcode of our products and simply displays our pre-assigned custom metafield "bin location". That's it. Anyone know if something like this exist? 

We simply want to do quick "put aways" of our inbound cross dock items.
