We have a problem with filling orders with the wrong bar coded boxes sometimes. The plan would be for the boxes to pass under a scanner that is connected to a database. Each case has an item bar code number, and a UPS shipping bar code. The scanner would have to be smart enough to read the UPS label, check the db to see what item numbers should be scanned, scan the item bar code on the same case, and then sound the alert it is the wrong item. I need a reputable company for the scanner and software. Anyone have something running like this? I don't know where to begin to look.
