Definition:

A QR code (Quick Response code) is a type of two-dimensional barcode that contains information about its origin and can be read by a camera-equipped device. It was first developed in Japan in 1994 for use in automotive industry as a tracking tool.

Importance and Use Cases:

QR codes have become increasingly popular worldwide due to their ability to convey large amounts of data, such as URLs, text messages, contact information, and even payments. Here are some key use cases:

Marketing and Advertising

• Businesses use QR codes on billboards, flyers, and product packaging to connect customers directly to their websites or social media profiles.
• Event organizers include QR codes in event promotion materials to provide instant access to tickets, schedules, or other essential information.

Retail and Commerce

• Stores display QR codes next to products to facilitate easy checkout, provide detailed product information, or offer exclusive promotions.
• E-commerce platforms use QR codes to enable fast payment processing, share inventory details, or facilitate loyalty programs.

Healthcare

• Medical institutions employ QR codes for patient registration, appointment scheduling, and sharing health records securely.
• Pharmaceutical companies use QR codes on packaging to provide quick access to instructions, warnings, or recall notices.

Travel and Tourism

• Travel agencies include QR codes in brochures, online ads, or travel guides to share destination information, itineraries, or booking links.
• Airlines and airports use QR codes for check-in, baggage handling, and boarding procedures.

How Do QR Codes Work?

Step 1: Creation

QR code creators use specialized software (like QRCode Monkey) to generate a unique QR code based on the desired information. This can include:

• URL links
• Text messages
• Contact details
• Payment information

Step 2: Embedding Information

The generated QR code contains the embedded data in the form of black modules (boxes). The size and shape of these modules are designed to be read by cameras.

Step 3: Reading the QR Code

A smartphone camera scans the QR code, which activates a reader app. This app deciphers the encoded information using a process called “decode”.
