Barkoodi-skannereid, also known as barcode scanners, are optical scanners that read and transmit information encoded in barcodes. The technology has become ubiquitous in modern commerce, inventory management, and point-of-sale systems.

The first barcode scanner was invented in 1974 by Norman Joseph Woodland and Bernard Silver, and it was later commercialized by Monroe Technology. The early scanners used a series of photo detectors to capture the reflected light from the barcode and decode the information. With the advent of laser technology, the scanners became more accurate and reliable.

Barkoodi-skannereid work by shining a light on the barcode, which reflects back to the scanner. The scanner then uses a digital signal processor to decode the pattern of light and translate it into a numerical code. This code can be used to identify the product, track inventory, or retrieve information from a database.

There are several types of barcode scanners, including handheld scanners, fixed-mount scanners, and imager scanners. Handheld scanners are commonly used by retail workers to scan products at the checkout line, while fixed-mount scanners are often used in industrial settings to track inventory. Imager scanners use a high-resolution camera to capture the barcode image, making them more accurate and reliable.

Barkoodi-skannereid have revolutionized the way businesses manage inventory and track products. They have also enabled the creation of self-checkout systems and mobile payment solutions. Despite their widespread use, barcode scanners continue to evolve with advances in technology, including the development of QR code scanners and other emerging standards.
