A barcode scanner (also known as a barcode reader) is an electronic device that can read printed barcodes, decode the data contained in the barcode to a computer, and return the results.
Barcode scanners are used in a variety of industries, including retail, manufacturing, and logistics. They are used to read barcodes on products, packages, and other items. The data from the barcode is then used to track inventory, process sales, and manage logistics.
There are two main types of barcode scanners: handheld scanners and fixed scanners. Handheld scanners are portable devices that can be held in the hand. Fixed scanners are mounted on a surface, such as a counter or a shelf.
Handheld scanners are typically used in retail stores and other environments where the scanner needs to be moved around. Fixed scanners are typically used in warehouses and other environments where the scanner is used in a fixed location.
Barcode scanners work by using a laser beam to scan the barcode. The laser beam reflects off of the black bars and spaces in the barcode. The scanner then converts the reflected light into electrical signals. These electrical signals are then decoded by the scanner into the data that is contained in the barcode.
The data from the barcode can be used to do a variety of things, such as:
- Track inventory
- Process sales
- Manage logistics
- Provide customer service
- Prevent fraud
Barcode scanners are an essential tool for businesses of all sizes. They can help businesses to improve efficiency, accuracy, and customer service.
