A barcode scanner is an electronic device designed to read and interpret barcodes. Barcodes are machine-readable codes consisting of a series of black and white stripes found on various products, packaging or labels. They are used to store and transmit information such as product codes, prices and stock levels.
Here is some important information about barcode scanners:
- Types of barcode scanners: there are different types of barcode scanners, including pen scanners, laser scanners, CCD (Charged Coupled Device) scanners and imager scanners. Each type has its own modes of operation and applications.
- Mode of operation: Barcode scanners use a light source (e.g. LED or laser) to illuminate the barcode and a sensor to detect the reflected light intensity. By interpreting the different light and dark areas of the barcode, the scanners can read the information it contains.
- Barcode types: There are different types of barcodes, including linear barcodes such as the EAN-13 (European Article Number) code and the UPC (Universal Product Code) code, as well as 2D barcodes such as the QR (Quick Response) code. Barcode scanners can usually read multiple barcode types, but some specialised scanners specialise in specific barcode types.
- Areas of application: Barcode scanners are used in a variety of areas including retail, logistics, warehousing, healthcare, libraries and more. They enable fast and accurate product data capture, inventory tracking and pricing.
- Wired vs. wireless: Barcode scanners are available in wired and wireless versions. Wired scanners connect to the computer or POS system via USB, RS-232 or PS/2 ports. Wireless scanners use wireless technologies such as Bluetooth or WLAN to connect to a receiving device.
- Integration and software: Barcode scanners can be integrated into various software and system environments. They often work with point-of-sale (POS) systems, warehouse management systems and other enterprise applications. The scanners deliver the scanned data as keyboard input or via special interfaces to the connected systems.
There are a variety of barcode scanner models on the market that differ in functionality, range, durability and price. The selection of a barcode scanner depends on the specific requirements and intended use. Give us a call, we will be happy to advise you!
