Barcode Reader Basics

The c# barcode reader is a laser-based optical scanner that can read written barcodes, decode the information contained in the barcode, and then send this data to a processing device, usually a personal computer. Like a regular flatbed scanner, however, it is made up of a laser source, a photodiodes lens and an optical sensor converting the optical impulses to electrical signals. The electrical signals are then converted into a series of voltage levels and sent to a circuit board which performs the tasks of a PC or keyboard. The circuitry in such a system is designed specifically to perform barcode scanning.

There are many different types of barcode scanner available for your business needs. Some are based on patented technology, while others are based on industry standards and practices. To best determine what type of barcode scanner is most suitable for your business, you need to do some basic research and analysis of your specific needs. Here are some factors to consider:

There are many types of bar codes, which can be scanned with bar code scanners. One of the most popular bar codes used in the retail environment are the barcodes used to indicate products in a sales environment. The barcode library which is available from most barcode readers can handle all barcodes within a standard 100 feet range, although longer ranges are possible. Here is an alternative post for more info on the barcode scanner in c#.

The majority of home barcode scanners operate using a method of parallel scanning. This means they read one bar code at a time. The laser barcode reader, also known as a parallel line scanner, is designed specifically to simultaneously scan all the horizontal lines, vertical lines, and any diagonal lines which are part of the standard 100 foot scan area. The other common type of barcode scanner is the optical scanner, which only has a vertical line limit.

Most barcode scanners employ a method called FOCUS MODE. This is a very convenient feature for those who may not have the ability to comfortably operate a keyboard while scanning. The FOCUS MODE scanner simply keeps the focus on one line at a time. When you are finished scanning, the barcode library will automatically close. 

Most barcode readers use computers to collect and store the information. In order to speed up the process, some of the newer barcode readers use memory. The data is stored on microchips that can easily be replaced when necessary. For even faster processing, many barcode readers use an AC adapter that plugs in to the computer.
