Defining the Concept

A QR code is essentially a digital tag that contains data which can be read by smartphones and computers using a special app or software. When you scan a QR code with your device, it will trigger an action, such as opening a website, sending an email, or even making a phone call.

Importance and Use Cases

QR codes have numerous use cases across various industries, including:

• Marketing: QR codes can be used to promote products, services, or events by linking to websites, social media pages, or landing pages.
• Healthcare: QR codes can contain medical information, such as allergy alerts or medication instructions.
• Logistics and Supply Chain Management: QR codes can track packages, shipments, and inventory levels.
• Retail: QR codes can provide customers with product information, pricing, and reviews.
