Over time, Quick Response (QR) codes have gained significant popularity as a tool for easy access to information. Therefore, it is important to know how to scan these codes on our devices. Scanning a QR code requires a few simple steps, whether you’re an iPhone or Android user. In this guide, we’ll walk you through the scanning process of a QR code on your iPhone or Android device in 2023.
What is QR code used for?
Do you ever wonder what those little black and white squares on a product mean? Those are QR codes! QR codes are two-dimensional barcodes to be scanned by devices to access website URLs, contact information, or product details. QR codes have become a popular marketing tool, and their applications are endless. So the next time you come across a QR code, take a moment to scan it to discover what information it can unlock.
Uses of QR Codes in everyday life
- Quick and efficient: QR codes offer a fast and easy way to access information without manual searching or typing. Scanning a QR code takes a few seconds.
- Enhanced security: QR codes have revolutionized how product owners and users approach product authentication and fraud prevention. Scanning a QR code on a product can confirm if a product is genuine or fake.
- Easy payments: You can make swift payments for goods and services by scanning a QR code without cash or a physical credit card.
- Transform marketing: QR codes are used in marketing and advertising to grant users exclusive offers, discounts, or other promotional materials.
How do QR codes work?
The process involves reading the black and white pattern of the code, which is made up of eight mask patterns. The QR code scanner uses an algorithm to choose the correct pattern with the least penalty score. QR codes can store a large amount of information, up to 7089 numeric characters or 4296 alphanumeric characters. For optimal scannability, it’s important for QR codes to have high contrast with their background, allowing the camera to read them accurately.
