Barcode scanner is a device that captures images and converts them into a digital format that the computer can display, edit, store, and output. Scanners can be used in a wide range of applications, such as combining art graphics and photo scanning into documents; scanning printed text into word processing software to avoid re-typing; scanning fax files into database software or word processing software for storage ; and add images to multimedia, and more.
The biggest advantage of the scanner is to replace the manual entry; its main function is also this; to enter a string of numbers, if there is a barcode without a scanner, then you have to manually enter a number, if the number is long, it is easy to make mistakes. With a scanner, click on it and the error rate is very low!
