QR codes, or Quick Response codes, are two-dimensional barcodes that contain information about the item they are attached to. They were first introduced in Japan in 1994 by Masahiro Hara of Denso Wave and have since become a ubiquitous technology used worldwide. In this article, we’ll explore how QR codes work, their importance, and step-by-step guide on how to scan them.

What is a QR Code?

A QR code is a matrix barcode that can store information such as text, URLs, email addresses, vCards, and even GPS coordinates. They consist of black squares arranged in a square grid on a white background. The code itself is read by a scanner, which decodes the information stored within.

QR codes have become increasingly important in today’s digital age. They offer a quick and easy way to share information between devices, reducing the need for manual typing or searching. Here are some key use cases:

• Marketing: QR codes can be used on posters, flyers, business cards, and even product packaging.
• Sales: QR codes can be used to provide detailed product information, pricing, and inventory levels.
• Customer Service: QR codes can be used to provide customer support contact details or FAQs.
• Education: QR codes can be used to create interactive educational content.
