What are Quick response codes? 

QR codes are capable of storing hordes of data. But, it does not matter how much valuable information they contain, when scanned with a mobile device, these codes enable users to access information rapidly, true to their name. A Quick Response code is basically a barcode that can be easily read by a device such as a mobile, and which stores information as a series of pixelated dots in a square formation. They are generally used to track product information in a supply chain. A lot of smartphones have in-built QR scanners and readers, these days. 

The thing with standard barcodes is that they are unidirectional, meaning, they can be read-only in one direction; top to bottom. Hence, they can store only a limited amount of information, in an alphanumeric format. But, a QR code on the other hand, is bidirectional, meaning, it can be read in two ways; top to bottom and right to left. This very fact allows it to store substantially more data. The data that can be stored in a QR code can include website URLs, phone numbers, or text. 

Where can QR codes be used? 

QR codes can be used for numerous operations. We have listed some of them below: 

  • Link directly to download an application on the App Store. 
  • Authenticate and validate online accounts and verify the login details
  • Access Wi-Fi by housing the details of encryption such as SSID, encryption type, and password. 
  • Send and receive payment details. 
  • QR codes can store information about your bank account or credit card
  • They can be used as 2-step verification passkeys
  • Websites can display a QR code that a registered user can scan with their mobile device and automatically gain access. 

How to scan a QR code? 

Scanning a QR code is not a herculean task, it is in fact, a child’s play. Most mobile devices have in-built QR scanners which are sometimes integrated with the device camera. A QR scanner is just a way through which you can scan any number of QR codes. Some older mobile devices may require a specialised app to scan QR codes. Such apps are easily available on the play store and do not require much hassle when downloading. Scanning a QR code is a straightforward and convenient process. Let us go over it: 

  • Open the QR reader/scanner feature on your phone. This feature can either be in your device camera or the settings of your phone. If you have a specialized application for the purpose, you can open that. 
  • Now, point the scanning interface at the QR code– you should be able to point your camera from any angle and still receive the relevant information. Your camera should just detect the QR code in the vicinity and you are good to go. 
  • Once your device camera detects and scans the QR code, it will instantly show you the required data on your screen. It can be a contact number, payment details, and so on. You can do the needful once you have scanned the QR code.
