You might have seen these QR codes from time to time and might have even used them. But do you know what exactly they are? They were first invented by a Japanese company called Denso Wave, a Toyota subsidiary. QR code stands for “Quick Response” code, a type of barcode that can be scanned by a digital device (smartphones and scanners).

In simple terms, QR codes store information as a series of pixels in a square-shaped grid. It does so by encoding kanji/kana, numbers, bytes, and alphanumeric characters altogether. They can store website URLs, phone numbers, and even up to 7089 or 4296 characters.

What else can it do?

Nowadays, all smartphones come with built-in QR code scanners, so it has become quite common to use them for day-to-day things. Especially in the covid era where usage of this technology has been more widespread than ever before. People can also use them for:

  • Authenticate online accounts
  • Sharing Online Payment Ids
  • Verify login details
  • Link to an app on the Apple App Store or Google Play.
  • Share Wi-Fi password
  • Store encryption details such as SSID, password, and encryption type.
  • Send and receive payment information.
  • And much more

QR code technology has been developing over the years and has even added traceability, brand protection, and anti-forgery measures. Its durability is also to be kept in mind, as even if 30% of the code is damaged, scanners can still read it.

How to make a QR Code?
