What is QR Code?

A QR code is a two-dimensional version of the barcode, typically made up of black and white pixel patterns. It was developed by Denso Wave, a Japanese subsidiary of the Toyota supplier Denso, for marking components in order to accelerate logistics processes for their automobile production. Now, it has found its way into mobile marketing with the widespread adoption of smartphones. “QR” stands for “Quick Response”, which refers to the instant access to the information hidden in the Code.

Does QR Code Save My Data?

QR codes are a type of two-dimensional barcode that can store a large amount of data, including text, URLs, and other information. The security of QR codes depends on the final destination of each code and not on the QR code technology itself. QR code technology has no security flaws and cannot be hacked. However, the security risks that we often associate with QR codes — phishing, hacking, or malware — stem from the final destination of each code. If sensitive data is shared via the QR code channel, it is advisable to grant access to the encrypted content to a select group of people and no one else. Secure QR reader apps display the content of the link to which is going to be navigated and check the link against a database of known malicious links. It is also important to pay attention to the URL being directed to and ensure that the links are legitimate.

QR Code Expire or Not?

QR codes do not expire and can be scanned indefinitely, unless they are physically damaged or edited.
