Quick Response (QR) codes are two-dimensional barcodes that can store a wide range of information, from text and URLs to contact details and even payments. In this article, we’ll explore what QR codes are, why they’re essential, and provide a step-by-step guide on how to access them on your phone.

What is a QR Code?

A QR code is a type of machine-readable code that consists of a square grid of black and white modules. It’s called “quick response” because it can be scanned and read quickly using a smartphone or other mobile device. QR codes contain information such as text, URLs, email addresses, phone numbers, or even coordinates for GPS navigation.

Importance and Use Cases

QR codes have become an essential part of modern life, with applications in various industries:

• Marketing: Retailers use QR codes to provide customers with discounts, promotions, or exclusive offers.
• Travel: Airlines and transportation companies display QR codes that allow passengers to access their boarding passes, check-in online, or receive travel updates.
• Healthcare: Medical facilities use QR codes for patient information, medical record sharing, and telemedicine services.
• Education: Schools and universities employ QR codes for student registration, course material distribution, and campus navigation.

Step 1: Open the Camera App

On both iOS and Android devices, you’ll find the camera app pre-installed. Locate it on your home screen or in the app drawer.
