Many parts of our lives have become digitized. Everything from ordering food to shopping can be done at home. To pay for all these, we often use QR codes and sometimes we hear the term bar code being used.
But have you ever tried to know what is the difference between these two? Many consider these two to be the same. But in reality, there is a lot of difference between these two. Today we are going to tell you about this.
What is a QR code?
In other words, the QR code is also known as Quick Response. Generally, it is considered an advanced version of the bar code. It is square. In this, more information can be stored simultaneously than in bar codes.
Usage: It is used to make payments.
What is a bar code?
Bar codes can store less information than QR codes. But this method has been going on for years. It was started in 1974 and it was introduced for commercial purposes. The bar code can be read through an optical device. A barcode is made up of parallel lines. These lines are its main identity.
Usage: Bar code is used to store information about any item. This is usually seen in products.
