QR Code and Its Origins  

QR codes were first introduced in 1994 by a Japanese company. This was invented for the purpose of tracking automotive parts and vehicles. It was developed from barcodes.

The creator did not purposely apply for a patent so that the technology can be used by anyone. Initially, however, the use of QR code was slow. This only became popular in the early 2000’s after the integration of QR code scanners in smartphones. Now, the use of QR codes has made its way to businesses across all industries.

They then stick it over real QR codes for legitimate businesses or campaigns. This may be in an ad poster, menu board or even grocery items. They can even launch fake contents or promotions using legitimate business names to spread the code and lure more victims.
