Using Bar Code Scanners

Bar code scanners can save labor in many situations. Checking in deliveries is much faster and more accurate than counting items by hand. You merely pick up an item, pass it in front of a scanner and put it into a tub to be shelved. Taking inventory also is much quicker and more accurate with a bar code scanner. You merely pick up items from the shelf, pass them in front of a scanner and put them back on the shelf.

I was interested in how automotive mass retailers sell with bar code scanners. The employees working the counter look up the parts using electronic cataloging on their Store POS System. Once they find the part, the employee goes to the shelf and picks up the part. The customer looks at the part and makes a decision whether to buy the part or not. Assuming the customer chooses to buy the part, it is put on a sell shelf and sold by a cashier using a bar code scanner. This guarantees that the part going out the door is the same part as is on the invoice. If the employee grabbed the wrong part by mistake the customer may be annoyed, but at least the Store POS System's inventory is correct. Contrast this with how many parts stores sell the same part. When they look up the part with their electronic cataloging, the Store POS System usually makes it convenient to put the part directly onto an invoice. If the employee picks up the wrong part by mistake not only is the customer annoyed, there are two mistakes in the Store POS System's inventory. One might think about using a system that is similar to that used by the automotive mass retailers.
