History of QR Codes

The now increasingly present utility in most business organizations was created by a Japanese engineer named Masahiro Hara in the year 1994 primarily to track and monitor vehicles and parts, along with the production process of a subunit of Toyota motor company. It was later applied on tickets during musical concerts and sports events.

Hara and his teammates turned a 1-dimensional brand into a 2-dimensional grid and now about 80 percent of the world’s population are proud users of this handy means of gaining information.


Types of Quick Response Codes

QR codes come in different sizes and are majorly categorized into static and dynamic QR codes.

1. Static QR codes: this type of code does not allow alteration or modification of already stored data. A very good example is the Wi-Fi password on your mobile. These types of codes are only for a time by a user and they come free, and that’s because no price is attached to them. However, these codes cannot be tracked by the number of times they were scanned, the type of device used for scanning, and its location. The static QR codes store data directly inside the QR code graphic and are more complicated than dynamic because they are complex to scan and compare.

2. Dynamic QR codes: this type of barcode permits modification of stored data. It is easily tracked alongside with real-time scanning, monitoring to know the number of times scanned, their locations and the types of versions. It also uses a short URL which redirects to the destination and very effective in marketing campaigns.

Common examples of QR codes : Image QR codes, Social media QR codes, Audio QR codes, Website QR codes, Business card QR codes, Facebook QR codes, WhatsApp QR codes, E-mail QR codes, Telegram QR codes, PDF QR codes etc.
