3. Education and Learning

In schools and universities, QR codes are used to share learning materials, submit assignments, or take attendance. Teachers can place a QR code on a slide, and students scan it to access digital content instantly — reducing the need for paper and improving learning experiences.

Hospitals and clinics are using QR codes to manage patient information, appointments, and even to give access to digital health records. During the COVID-19 pandemic, QR codes were widely used for health declarations, vaccine certificates, and contact tracing.

5. Travel and Transportation

From boarding passes to e-tickets, QR codes have simplified the way we travel. Passengers can check in at airports or board trains by scanning a QR code on their phone, eliminating the need for printed tickets.
