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 QR codes and explore the capabilities of iPhone cameras.
What are QR Codes?
Before we dive into the world of iPhone cameras, let’s first understand what QR codes are. 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 are made up of a series of black and white modules arranged in a square grid. The modules are arranged in a specific pattern to represent the data stored in the code. QR codes can be used for a variety of purposes, including:
- Making payments: QR codes can be used to make payments at stores, restaurants, and other merchants.
Can iPhone Cameras Scan QR Codes?
