What type of technology does Bar Code use?

Bar Code technology employs transverse scanning to read characters, capturing data in the form of patterns or bars that can be identified by scanners. Barcodes typically consist of a series of vertical bars and spaces that represent numbers or letters, allowing for efficient data capture and processing. The scanning process relies on the interpretation of these visual patterns, confirming that transverse scanning is indeed a fundamental aspect of how barcodes function.

Optical character recognition, while related to reading printed text, is not specifically how barcodes operate, as barcodes are not designed for interpreting alphanumeric characters at a granular level. Similarly, magnetic strip encoding pertains to magnetic strips on cards that store data through a different mechanism, and non-contact RFID technology involves radio frequency tags that do not rely on scanning visual patterns at all. Hence, the primary method of reading barcodes is through transverse scanning, employing optical technology to read the arrangement of bars and spaces.
