UPCs (Universal Product Codes) were developed for the grocery industry to help them keep tabs on their inventory. It was valuable technology that then was embraced by all retailers. Each UPC has a six digit manufacturer code followed by the item number which is the next five digits. The final digit is a check code to make sure the code is really for the item which was scanned. This prevents the consumer from removing a code from one product and trying to make it work on another.
They use a computer to scan the item's bar code and the item will be on the screen.

The Metrologic barcode scanner is one of the most popular barcode scanners. These scanners are widely used in grocery stores and hardware stores. They allow the ability to scan barcodes to bring up product information for purchases or additional information about a product.
The PDA barcode scanner works by scanning the unique barcode attached to every item and searching it's database to find the corresponding information related to the product scanned. It reads the barcode by illuminated the barcode with red light and the sensor found within the PDA detects the reflected light.
The sensors in a barcode scanner reads the bars and convert them to electrical pulses. Since each strip of bar is equivalent to a character, they can be displayed on a monitor. The whole process is really very quick. Milliseconds quick.
A bar code laser scanner works by shining a bright light (laser light) at the barcode and measuring the reflected beam. In order to scan the entire barcode very quickly, the light is bounced off a spinning disk to cover the entire barcode in one pass.

The red light that emanates from the barcode scanner illuminates the barcode. That light is reflected back to the scanner which has a sensor inside. The sensor detects the amount of light reflected and is thus able to translate the pattern of lines into something meaningful.

Barcode readers are everywhere, and everyone has come into contact with one at some point in their life. Whether they’re using the self-scan at the grocery store, or trying to look up the price of an item in a larger department store, the barcode scanner has come in handy. Another place where barcode scanners can be extremely helpful is the heart of a home-based business. Small businesses, especially those based in the home, rely heavily on barcode scanners to keep their inventory, which is a huge part of staying organized. And staying organized is a huge part of becoming and remaining successful. Home-based businesses need every advantage they can get, and relying on a home barcode scanner is a great way to stay ahead of the game. Just because the business doesn’t move large quantities of products doesn’t mean a barcode scanner won’t be useful. It can help keep the business in line. Finding the right home barcode scanner can be a bit of an undertaking, but at the same time, it’s a necessary process. Your first step is going to be deciding what type of inventory your home-based business needs to take. If you’re a retail shop, you may want to get a more heavy duty scanner than if you’re simply trying to keep track of your spending. Most of these can be quite large. You may have seen examples of them in the checkout lanes at large department stores. Either way, you’ll be able to find a scanner and a computer software program that will help keep you in line. Next, you need to figure out how much scanning you’re going to do. If you’re going to be scanning a lot, then you may want to gravitate to one of the larger, hand-held barcode scanners. If not, a smaller model, like a pen- scanner, would probably work perfectly. Prepare yourself to spend between $50 and $200, depending on the size of the scanner you select. Either way, obtaining a barcode scanner for your home-based business is going to help keep your life organized, paving the way for success, no matter what type of business you run.
2D Barcode Scanner should be used if the data is large and cannot be represented by the 1D barcode. Examples of 3D barcode scanners are PDF417 used in ID cards and licenses, QR codes in reliability cards, data matrix codes in healthcare and related products, Maxi macode in the packaging industry, and Aztec code in rail and aviation.
