The process of reading a barcode entails detecting the code and converting it to a digital representation with the help of a . The most typical way involves aiming the light at one portion of the code at a time and reading the reflected light using a light sensor.
A dark area will reflect less light than a light-colored area. The sensor detects the difference and sends it to the computer. The thickness and spacing of the dark and light parts determine the code. A single LED light and light sensor are used in a very basic barcode scanner. The user would have to slide the reader directly over the code in this situation.
While you may prefer to use automation to do tasks, you can also provide barcode scanners to your employees so that they may enter things into your inventory database when they arrive. The scanners on hand are quite simple to operate, so all you'd have to do is gain a feel for how to use one and then pass that information on to others. The software makes the procedure as simple as scanning a barcode, but it also needs to know if the product is coming in or going out.
