Bar code readers primarily use laser or imaging technology to sense and decode input. Laser-based scanners emit a laser beam that reflects off the barcode, while imaging scanners capture a digital image of the barcode and analyze it. Both types convert the reflected light or image data into electrical signals that are processed to extract the encoded information. Additionally, some readers may use infrared or CCD (Charge-Coupled Device) sensors for enhanced reading capabilities.
