In today’s digital age, QR codes have become an integral part of our daily lives. From making payments to accessing information, QR codes have made it easier for us to interact with the world around us. But have you ever wondered if your iPhone camera can scan QR codes? In this article, we’ll delve into the world of iPhone cameras and explore their QR code scanning capabilities.
Understanding QR Codes
Before we dive into the iPhone camera’s QR code scanning abilities, let’s take a brief look at what QR codes are and how they work. QR codes, or Quick Response codes, are a type of matrix barcode that stores information, such as text, URLs, or other data. They were invented in the 1990s by Masahiro Hara, an engineer at Denso Wave, and were initially used to track parts in manufacturing.
QR codes work by using a series of 0s and 1s to represent the data stored within them. When a smartphone camera scans a QR code, it detects the pattern of 0s and 1s and decodes the data, allowing the user to access the information stored within the code.
Early Days of QR Code Scanning on iPhones
In the early days of iPhones, scanning QR codes was not a built-in feature. Users had to download third-party apps, such as Scan or QR Code Reader, to scan QR codes. These apps used the iPhone’s camera to detect the QR code and decode the data stored within it.
However, with the release of iOS 11 in 2017, Apple introduced a built-in QR code scanner to the iPhone camera app. This feature allowed users to scan QR codes without the need for third-party apps.
