Overall, using QR codes really is simple, and with the right app and a little know-how, you can start and use them for all kinds of practical or promotional purposes.
Introduction: QR code technology
QR codes are ubiquitous in today’s world. You can see them everywhere – from billboards to product packaging, business cards, and even on websites. They are efficient and handy in sharing information with others. QR codes, also known as Quick Response codes, are two-dimensional barcodes that can be scanned using a smartphone or a tablet. They were first developed in Japan in the mid-nineties for tracking inventory in factories, but have now become a marketing tool and a convenient way to share information.
How do QR codes work?
QR codes work by encoding information into a visual pattern that can be read by a machine. Essentially, data is stored in the QR code as a black and white grid pattern. The mobile device’s camera picks this up, and special software is used to decode the pattern, which results in the display of text, images, and other types of media. A web link contained within a QR code can be scanned, and it will take the user directly to a website without them having to type in the URL manually.
Is a smartphone necessary to use QR codes?
To utilize QR codes, you require a smartphone or tablet equipped with cameras. Unlike traditional barcodes, which can be read by barcode scanners, QR codes require an optical reader app on the device. Most modern smartphones and tablets come equipped with a QR code reader. However, if your device does not have one, you can go to your app store and download one at no cost.
Types of smartphones and tablets that support QR codes
QR code reader software is compatible with both iOS and Android operating systems. This means that nearly all modern smartphones and tablets support QR code scanning. A few examples of phones that support QR code scanners are:
- Apple iPhone, starting from iPhone 4S, running on iOS 7 or higher.
