Fixed barcode scanners are available in a variety of types, each with its own advantages and disadvantages. Here are some of the most common types:

In-counter scanners: These scanners are designed to be installed into a counter or other surface, with the scanning window flush with the surface. They are often used in retail environments and are designed to scan items as they pass over the window.

On-counter scanners: These scanners sit on top of a counter or other surface and are often used in retail and healthcare environments. They are designed to be easily accessible to users and can scan a wide variety of barcodes.

Presentation scanners: These scanners are similar to on-counter scanners but are designed to be held by a user and pointed at the barcode. They are often used in retail and other environments where items need to be scanned quickly and efficiently.

Industrial fixed scanners: These scanners are designed for use in industrial and manufacturing environments, and are often ruggedized to withstand harsh conditions. They may be mounted on a conveyor belt or other equipment and are designed to scan barcodes as items move past.

Miniature fixed scanners: These scanners are small and lightweight, making them ideal for use in tight spaces or on mobile equipment. They may be used in a variety of environments, including retail and manufacturing.
