QR codes have revolutionized the way we interact with digital information. These two-dimensional barcodes contain information such as text, URLs, email addresses, phone numbers, and even geolocation data. In this article, we’ll explore how to scan QR codes in Telegram, a popular messaging app used by millions worldwide.

What are QR Codes?

QR codes (Quick Response codes) were first introduced in 1994 by Masahiro Hara of Denso Wave. They were initially designed for use in manufacturing and inventory control, but their popularity soon spread to other areas. Today, QR codes can be found on various surfaces, from product labels to advertisements.

A QR code consists of a square grid of black and white modules (squares). The pattern of these modules conveys the stored data. When scanned with a smartphone or tablet, the QR code reader decodes the information and opens it in a relevant app or browser.

Importance and Use Cases

QR codes have numerous practical applications:

1. Marketing: Businesses use QR codes to promote products, share discounts, and engage customers.
2. Travel: Travelers can scan QR codes for directions, restaurant reviews, and attraction information.
3. Healthcare: Patients can access medical records, appointment reminders, and health tips using QR codes.
4. Education: Students can scan QR codes to access educational content, online resources, and virtual tours.
