What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store information such as text, URLs, contact details, or even attach a video file. They were invented in 1994 by Masahiro Hara of the Japanese company Denso Wave to track parts during manufacturing.

Importance and Use Cases

QR codes have become increasingly popular due to their versatility and ease of use. Here are some practical use cases:

• Marketing: Businesses can use QR codes on promotional materials, such as flyers or billboards, to direct customers to a website or social media page.
• Payment: Some retailers allow customers to pay using QR codes, which eliminates the need for physical contact and reduces the risk of card skimming.
• Event Promotion: Event organizers can use QR codes to provide attendees with important information about the event, such as schedules, maps, or speaker profiles.
• Personal Use: People can create their own QR code to share personal details like phone numbers, email addresses, or social media profiles.
