Understanding QR Codes
Before diving into how to scan QR codes from your camera roll, it’s vital to understand what QR codes are and why they are so popular.
The Basics Of QR Codes
QR, which stands for “Quick Response,” was invented in 1994 by a Japanese company called Denso Wave. Unlike traditional barcodes that can only hold a limited amount of data, QR codes can store various types of information such as URLs, text, email addresses, and more. Due to their ability to store significantly more data and their quick readability, they have become staples in marketing, retail, and logistics.
How QR Codes Work
QR codes contain three main elements:
– Finder Patterns: These are the large squares at three corners of the code that help scanners identify its position and orientation.
– Alignment Patterns: These assist in correcting any distortion in the QR code being scanned.
– Data Modules: The smaller colored squares that encapsulate the actual information.
When scanned, QR codes convert the visual data into a readable format for smartphones or QR code readers.
