Quick Response (QR) codes are transforming healthcare by streamlining operations, reducing errors, and enhancing communication between patients and providers. Their ability to instantly store and share information simplifies administrative workflows, saves time, and allows clinicians to focus more on patient care. QR codes also strengthen patient education by granting easy access to service details, procedures, and treatment plans. When embedded in prescriptions, medical records, or lab results, they enable patients to retrieve personalized health information quickly and securely.   This paper examines the integration of QR codes across healthcare infrastructures, including patient identification, real-time monitoring, equipment tracking, and drug management systems. It highlights how QR codes improve hospital workflows while also addressing data privacy and cybersecurity concerns. To safeguard sensitive records, the study explores pairing QR codes with blockchain technology, creating a secure framework that restricts fraud, prevents identity theft, and ensures trust in healthcare data exchange. By merging the accessibility of QR codes with the robust protection of blockchain, this approach seeks to balance innovation, efficiency, and security—ultimately advancing a more reliable, patient-centered healthcare system.   Furthermore, the paper emphasizes the future potential of QR code adoption in advancing digital healthcare ecosystems. As telemedicine, IoT-enabled devices, and AI-driven diagnostic tools become increasingly prevalent, QR codes can act as critical connectors, ensuring seamless data flow across platforms. By supporting interoperability, reducing reliance on manual documentation, and reinforcing data integrity, they can contribute to building smarter, more resilient healthcare infrastructures that empower both providers and patients in the era of digital transformation.
