No, the response to this inquiry about barcodes is posed very frequently. There are a lot of older barcode scanners that utilize lasers as their light source. However, these lasers are Class 1 lasers, which are the safest form of lasers. In point of fact, CD players (remember when they were popular? ), along with other types of optical disc drives, employ Class 1 lasers.
Even though optical or image-based scanning technology is used by the majority of current devices to read barcodes, there is still a role for devices that utilize laser technology. The most common uses are industrial, such as in sortation plants, where laser-based devices perform very well while scanning barcodes from a greater distance. In general, lasers have been removed from locations like retail stores where customers may readily get their hands on them.
