What are QR codes?
QR codes (short for quick response codes) are two-dimensional codes that store data in a compact, scannable format. Originally developed by Denso Wave in Japan in 1994, these codes have revolutionized the way businesses and consumers connect to digital content. Using a QR code scanner, most smartphones can scan QR codes to instantly access websites, apps, or other digital destinations.
How QR codes work
A QR code consists of dark areas and light areas arranged in a grid pattern. When scanned using a phone or code reader, the embedded data is decoded and executed as an action—such as opening a web page, displaying text, or processing a mobile payment. Thanks to QR code technology, users can quickly and easily access detailed information without typing long URLs or instructions.
Key QR codes facts
QR codes have become an essential tool across industries, enabling seamless interaction between businesses and consumers. Below are some key facts showcasing the impact of QR codes.

This shift not only minimizes waste but also provides consumers with a more convenient way to access information and services.
Widespread payment method
Many businesses now accept QR code payments, streamlining transactions for both merchants and customers. Mobile payment solutions like Apple Pay, Google Pay, and WeChat Pay leverage QR code technology for secure and contactless transactions. The rise of QR-based payment systems is transforming the way people shop, dine, and conduct financial transactions worldwide.
Popular in events and ticketing
QR codes have replaced traditional paper tickets for concerts, transportation, and conferences. Event organizers use QR codes for quick check-ins, digital ticketing, and real-time event updates. This shift not only enhances security by reducing ticket fraud but also improves the overall attendee experience by eliminating the need for physical passes.
Improved consumer engagement
Businesses use QR codes to provide product details, special promotions, and interactive experiences. QR codes can link customers to exclusive content, discount codes, and immersive brand experiences. For example, QR codes on product packaging can direct users to instructional videos, customer reviews, or personalized recommendations, enhancing engagement and brand loyalty.
Used in healthcare
Hospitals and medical facilities use QR codes for patient records, appointment scheduling, and prescription information. The integration of QR codes in healthcare streamlines administrative processes, improves patient communication, and enhances access to essential medical data. Patients can scan QR codes to retrieve test results, medication instructions, or telehealth appointment links, making healthcare more efficient and accessible.
Use cases of QR codes
While QR codes are already deeply embedded in various industries, here are some possible applications that could further expand their potential:
1. Enhancing customer engagement
A restaurant places QR codes on its menu, allowing customers to scan for ingredient details, nutrition facts, and recommended wine pairings. This interactive feature provides diners with valuable information about their meals, enhancing the overall dining experience. Additionally, QR codes can be linked to feedback forms, enabling customers to share their opinions and rate their dining experience.
2. Smart business cards
A professional adds a QR code to their business card, linking directly to their LinkedIn profile or personal website for easy networking. This eliminates the need for manual contact entry and ensures that business connections have immediate access to up-to-date information. Companies can also use QR code-enabled business cards to link to portfolio websites, video introductions, or appointment booking systems.
3. Contactless payments
A small retail store uses QR codes for cashless payments, reducing the need for physical currency transactions. Customers simply scan the QR code to complete their purchase using their preferred digital wallet, making the checkout process seamless and efficient. This method also enhances hygiene and security, especially in high-traffic areas where contactless solutions are preferred.
4. Interactive advertisements
A billboard in a busy city center includes a QR code that directs users to a limited-time promotional offer or an interactive video. Marketers can track engagement metrics, allowing businesses to assess the effectiveness of their advertisements. QR codes in advertising can also drive customers to social media pages, sign-up forms, or virtual try-on experiences.
5. Real estate listings
A real estate agent places QR codes on ‘For Sale’ signs, allowing potential buyers to instantly view home details and virtual tours. This provides prospective buyers with relevant information on demand and enhances their property search experience. QR codes can also be used in open houses to provide interactive maps, mortgage calculators, or agent contact details.
6. Educational resources
Schools and universities use QR codes in textbooks and handouts, linking students to additional online resources, tutorials, and video lectures. Teachers can enhance lesson plans by embedding QR codes in classroom materials, directing students to interactive exercises, quizzes, and collaborative forums.

Public buildings have QR codes that provide emergency exit routes and important safety instructions. In disaster-prone areas, QR codes can be placed on signage to offer real-time updates, evacuation plans, and emergency contacts, ensuring that individuals receive the most relevant safety information quickly.
