I used small pocket sized barcode scanners that simply scanned to internal text file. I then used vba in excel to extract data (the scanner mounts as a drive). Once in VBA i got it to do all sorts of automated things and compare with our online parts systems. If as you implied, each part is individually barcoded then you could scan every barcode then use vba to count how many of each unique barcode it found. If not individually barcoded, then just scan the bin barcode as many times as there are parts in that bin. It means that the button gets pressed 50 000 or 1000 times if there are 5 scanners in the wild. The ones we used had buttons to remove the last entry. Additionally for errors or quick quantity addition you could have a print out of your home made barcode code (is used the free barcode font) that you can scan, such as -1, x2, x5, x10 etc. Then VBA uses those code to do the post processing. The closest image match I could find online for the ones we used were Symbol CS1504, They are cheap and charge when connected via usb. I never had one go flat. They turned a 2 person day task into single person 30mins. No longer having to data enter each item found or find it in a massive list to cross it off. It also could scan barcodes that were visually out of reach or where the numbers were human unreadable. Obviously badly damaged is no go but impressive to see what it could scan. It did find a couple of items that we had thought lost.
