QR codes have become ubiquitous in modern society. It seems every establishment asks you to scan the QR code to participate fully in its services. If you want to understand exactly what this means, read on.
What is a QR code?
A QR code is a type of barcode that appears 2D, but which you can scan with any smartphone or similar device to connect you to a wider digital world. QR stands for quick response. Most QR codes appear as black dots on a white background with larger squares at three corners.
History of QR codes
The history of QR codes can be traced back to 1994 Japan. Masahiro Hara of Denso Wave developed them to trace car parts through different stages of the manufacturing process. Like a barcode, you could scan it rather than the lengthier process of typing in digits, but it had considerably larger data capacity.
Their popularity soared in the early 2020s as digital technology generally became widespread and the Covid-19 pandemic saw an increased need for interactions without physical contact.
Uses of QR codes
Businesses use QR codes to manage stock by tracking locations and amounts, to allow customers to view product information by scanning packaging, to preserve restaurant hygiene through contactless menus, and to analyse customer engagement with advertising campaigns. They may be integrated with call buttons, such as those found at https://www.dinggly.com/products/wireless-call-buttons/.
Now that you understand QR codes better, you may be able to utilise them more effectively, or at least appreciate them more when you encounter them out on the street.
