Definition of fixed barcode scanner

An embedded barcode scanner (also called an integrated scanner or engine) is a compact module designed to be

permanently built into a larger device or system. Unlike handheld scanners, it lacks a physical trigger or housing meant

for user interaction. Its function is to automatically capture and decode barcode data for the host system.
 

Features of fixed barcode scanners

Form Factor: Small, board-level or compact module (often PCB-mounted).

No Standalone Housing: Requires integration into a host device (kiosk, POS terminal, vending machine, medical

device, robot, etc.).

Fixed Mounting: Typically installed in a specific orientation within the host.

Automatic Scanning: Scans continuously, on sensor trigger (e.g., object presence), or via software command from the host.

Direct Integration: Connects electrically and physically to the host's mainboard/power.

Interface Focus: Uses low-level electronic interfaces (USB HID, USB CDC/VCP, UART/RS232, TTL, I2C, GPIO).
