What does QR code stand for?

QR code stands for "Quick Response" code—a registered brand of Denso Wave, invented in 1994.

It's a 2D (two-dimensional) bar code readable by computers (having a webcam), smartphones, and tablets. In a single QR code, you can encode 4296 characters. However, once it is generated, you cannot alter it. If you attempt to change a code, it will result in a different QR code being produced.

The QR code consists of black squares with various vague patterns organized in a square grid on a white background. The data is extracted from those fuzzy patterns.

It uses four standardized encoding modes.

1. Numeric
2. Alphanumeric
3. byte/binary
4. Kanji

History of QR codes

The first time, a QR code was used in the automotive industry in Japan. Denso Wave invented it in 1994. Its invention gained fast popularity in the market because of its ability to store more data and easy readability. At the start, the QR code was used for time tracking, product tracking, product identification, document management, and marketing.

Today you can use the QR codes both for personal or commercial purposes. You only need to download a suitable application to read those codes on a smartphone. Usually, the QR code reader application is available in all types of smartphones.

Static QR Codes vs Dynamic QR Codes

You cannot change the static QR codes. Once it's created, the information stored in it is fixed. And it does not allow changing of the targeted URL or address of the data once generated. Furthermore, it does not enable you to track the scans' data and only leads you to one URL. The static QR codes are only helpful for personal use. They are not beneficial for business use because of their limitations.

On the other hand, you can change the dynamic QR codes. Once it's created, the information stored in it is alterable. You can track the data, and you can edit your URL or targeted content at any time. For marketing purposes, dynamic QR codes are more valuable. You can track the QR code and track the number of scans. When the user scanned, you can track the scan location (city, country) and user's device type (Android, iPhone).

But the question is, can you switch from a static to a dynamic QR code?

The answer is NO. Once the static QR code is created, you cannot switch it to a dynamic one. The static and dynamic QR codes are pretty different from each other.
