Nowadays QR codes are being used to display text to users, to save a vCard contact information to the user’s smartphone, to open a website URL, to code payments, for website login (ex: WhatsApp web login) or to compose an e-mail or text message just by scanning a QR code. You will be surprised to know that the QR code was invented back in 1994 by Denso Wave. It was initially developed for the automotive industry in Japan, but now it is being used by many companies. QR code (or Quick Response code) is a matrix bar code which can be read by an imaging device (camera) and then processed to read its data. I will also try to cover all the potential security issues related to QR codes.
In this article, I will discuss QR codes in details. This is why scammers are now using malicious QR codes for tricking users. But most users are not aware that QR codes can also be malicious. This is why people like to use QR code scanning for general tasks. For example, scan a QR code and save the business card details in your smartphone. With the scan of a QR code, we can perform various tasks which would otherwise need a lot more effort. Due to fast readability, it is now widely accepted. Our smartphone camera can easily read it with the help of a QR code scanner app. It is very similar to a bar code we see in products, but it does not need a different reader. So, many people now know what QR code is, but still more are unaware.
Recently, WhatsApp launched its web version, which needs QR code scanning to access the web version of WhatsApp. With the increasing use of smartphones, QR codes are becoming popular.
