Uses of a QR Code
Here are some broad examples where a QR code can be used:
- Professional Information: Say you want to build a personal brand. Then, there must be some way in which people can reach out to you for business. Traditionally, this is done via giving out an email address or a phone number. However, using a QR code, all such information to contact you can be stored in one place and anyone interested can scan it to read that information.
- Storing URLs: Businesses whether small or large, use some kind of websites or blogs to spread awareness about their product and generate leads. This URL, if directly typed onto a product, is not efficient enough. A better way would be to embed the URL in a QR code so that the user is redirected to the website itself on scanning the QR code.
- Banks and Payment: Understanding this can’t be difficult if you have used the Paytm scan code to make payments. It is nothing but a QR code with information about a person’s/business’s bank details. Imagine how inefficient it would be if people had to manually tell or write down bank account details for making small payments.
- Connecting to a Wi-Fi Network: If you go to a cafe and need to use their Wi-Fi, you will usually find a QR code that you can scan to connect to the Wi-Fi. This eliminates the need to know the Wi-Fi password. Simply saying, this QR code will have all the details like password, encryption Id, etc.
- Authentication: Once registered, a user can simply scan a QR code to log in every time. QR codes are also used for two-step verification and for logging in to several web versions of apps like WhatsApp and Telegram.

Ever opened WhatsApp on your PC or Laptop by scanning a black square box that seems to be colored unevenly in pixels? Well, that square box is nothing but a QR code. QR code is a 2-Dimensional bar code in the form of a matrix. It is like a label that can be read by machines to fetch the needed information they contain. Just like a barcode, which is 1-dimensional, is read using a scanner, a QR code can be scanned using our phones.
