Introduction
Have you ever seen a black and white square with a bunch of tiny squares inside it on a product, poster, or website? That’s a QR code, and it’s becoming more and more prevalent in our daily lives. In this article, we’ll explore what QR codes are, their uses, and most importantly, how to scan them with your smartphone. This article is aimed at anyone who has never scanned a QR code before or is unsure of how to do so.
What are QR codes and how do they work?
A QR code (short for Quick Response code) is a two-dimensional barcode that can be read by a smartphone or QR code scanner app. QR codes store more data than traditional barcodes, including website URLs, email addresses, phone numbers, and even entire documents.
QR codes were originally developed in 1994 for the automotive industry, but they have since been adopted by many other industries, such as retail, entertainment, and healthcare. They are used for everything from product packaging and billboards to event registration and patient records.
How to scan a QR code: Step-by-step guide
Ready to scan your first QR code? It’s surprisingly easy! Here’s a step-by-step guide:
Step 1: Open your smartphone’s camera app
Most smartphones today come with built-in QR code scanners. Open your camera app and make sure it’s set to photo mode.
Step 2: Point the camera at the QR code
Aim your camera at the QR code, making sure it’s in focus and fully within the frame. If the QR code is on a curved or shiny surface, you may need to tilt your phone to get a better angle.
Step 3: Wait for the QR code to be recognized
Your phone should automatically recognize the QR code and display a message or notification with its contents. If nothing happens, move your phone a little closer or farther away from the code.
Step 4: Follow the link or instructions
Once your phone has scanned the QR code, it will usually display a link or instructions related to the content of the code. For example, if the QR code is for a website, your phone will prompt you to open the link in your web browser. If the QR code is for a document, your phone may prompt you to download it.
That’s it! You’ve successfully scanned a QR code.
