Best Barcode Scanners

How do barcode scanners work?

The barcode scanners use light source, sensor, and decoder to read bar codes and send the data to a checking terminal or computer, where the codes are identified by using a product database. Deepening on their type, the barcode readers can use CCD scanners, lasers, cameras, or photodiodes and could have different connection interfaces.

What are the benefits of buying a barcode scanner?

The barcode scanners make keeping track on sales and inventory much easier task and they are widely used in the retail industry, manufacturing facilities, mailrooms, and hospitals. They can help their users increase productivity, improve the efficiency of the day-to-day operations, cut cost, and reduce errors.

What barcode scanners are available and what are their features?

Deepening on the technology that they use, the barcode scanners are divided into a number of groups: Pen type scanners use photodiodes and are light and easy to use. Laser scanners are very accurate since they use laser beams as a light source and photodiodes to measure the intensity of the reflected light.

The CCD scanners use multiple small light sources and they are measuring the emitted light from the barcode label rather than the reflected light. The omni-directional scanners typically also use laser, but they have more than one light source and are ideal for the retail industry as they are capable of reading barcodes quickly and often could read wrinkled, damaged, or poorly printed labels. Camera-based readers use tiny video cameras and image processing technology to read the labels.

Depending on their housing units, the barcode readers are handheld, pen, stationary, fixed-position, cordless, automatic, and PDA reader. Each one of these types has its advantages, where the pen and handheld scammers are ideal where mobility is important and the fixed scanners are perfect for checkpoints and mailrooms.
