What is a QR Code

QR codes have simplified our lives. All a user has to do is scan the QR code provided by the merchant, enter the amount, select the preferred mode of payment, and complete the transaction. Furthermore, a user can send money to another person simply by scanning the QR code provided by the recipient.

This blog will explain what a QR code is, as well as its different types and advantages.

What Is a QR Code?

The QR code (Quick Response) is a type of matrix barcode that is used to make payments to various merchants and owners. To complete transactions, smartphone cameras or QR scanners can be used to read a QR code.

  • A QR code allows you to complete transactions in seconds
  • QR codes are created using standardized encoding modes such as byte/binary, numeric, and alphanumeric
  • Merchants and individuals can share QR codes to receive money online
  • Users with smartphones and a digital payment app installed, such as Paytm, can scan any QR code and make online payments
  • QR codes are a digital payment method that can only be used for digital transactions
  • Paytm’s QR scanner can also read third-party QR codes, eliminating the need to open a separate application or QR scanner to read the QR code

What Are The Types Of QR Codes?

QR codes are classified into two types, each with its own set of uses. Let’s take a look at the types:

Static QR Codes 

Static QR codes are fixed QR codes that contain information that does not change. These codes typically encode a specific set of data, such as a website URL, contact details, or a pre-defined message. Once generated, the information within the static QR code cannot be modified.

Example of a static QR code: A restaurant may use a static QR code on their menu to provide a direct link to their website. Customers can scan the code using a QR code reader app on their mobile device, which will then open the restaurant’s website in their web browser. 

Dynamic QR Codes

Dynamic QR codes are QR codes that can be edited and updated with new information even after they have been created. This means that the encoded data can be modified and redirected to different content without changing the physical appearance of the QR code itself.

Example of a dynamic QR code: A company may use a dynamic QR code on their product packaging to provide customers with up-to-date information. They can update the code to redirect users to different landing pages, promotional offers, or even change the content based on the location or time of day.

What Are The Benefits Of QR Codes?

Other than being a quick payment mode, a QR code offers listed benefits too-

Easy To Use
