You may also find QR codes on the packaging for some of your favorite products.

These QR codes can reveal information about the product, such as nutritional information or special offers you can use next time you make a purchase. QR codes were initially invented to help track parts in vehicle manufacturing, and they are still used throughout the manufacturing industry.

You'll also find QR codes used by other businesses that need to keep a close eye on products and supplies, such as the construction, engineering, and retail industries. Postal services around the world also use them. Because they can contain a large amount of information, they are often relied upon to track parcels.

QR codes are also used in schools and colleges to help engage with students. They have appeared everywhere, from the classroom to the library, for tasks such as helping students find the books they are searching for.

Kaspersky QR Scanner instantly checks that a scanned link is safe before submitting any information to you. The scanner provides QR code authentication and alerts you to potential dangers behind a QR code, such as:. It also creates a log of past scans so that, if necessary, you can trace back to see when and where you may have been compromised.

Parts and bits whirred down conveyor belts and sped through factories with ever-increasing speed. It was fine for grocery store checkouts in the s, but it became a major bottleneck for s manufacturing. UPC barcodes are one-dimensional.
