Collection: Innovative Applications of QR Codes Across Industries
Original article: https://cli.im/article/detail/2107
Statistics show that over 10 billion QR codes are scanned globally each day, with China accounting for approximately 90% of global QR code usage. The average Chinese citizen scans QR codes more than six times daily.
As the "digital ID card" in the era of IoT, QR codes have become an integral part of daily life through applications in logistics, manufacturing, event check-ins, mobile payments, catering services, asset management, and marketing.
Why are QR codes so prevalent in China?
Beyond established habits like mobile payments, experts and scholars are exploring QR codes as development tools. By integrating QR codes with various operational and lifestyle needs, continuous innovation emerges through academic research papers that explore practical implementation scenarios.
QR Codes + Healthcare: New Approaches for Chronic Disease Management
With 240 million chronic disease patients in China (projected to exceed 300 million by 2025), there's urgent demand for low-cost, lightweight solutions with high public familiarity.
As early as 2019, researchers from the Thoracic Oncology Department of Zhejiang Cancer Hospital conducted a study with 80 post-esophagectomy patients. The control group received traditional health education through face-to-face instruction and printed materials, while the observation group used CaoLiao QR codes for nursing intervention.
Results showed 75% of observation group patients achieved ≥80% disease knowledge retention, significantly higher than the control group's 37.5%. In The Impact of CaoLiao QR Code Health Education on Postoperative Recovery of Esophageal Cancer Patients, researchers concluded: "Combining verbal education with QR code-accessible resources effectively improves health knowledge mastery, daily living capabilities, and self-management skills, accelerating postoperative recovery."
Similar applications were explored by Zhejiang Taizhou Hospital's General Surgery Department. They embedded nursing tutorial videos in QR codes, encouraging patients and families to scan and learn. Follow-up assessments revealed QR code-assisted management significantly enhanced disease knowledge and self-care capabilities while reducing ostomy complications.
These implementations demonstrate QR codes' role as information gateways bridging physical and digital realms. Healthcare professionals creatively leverage QR codes to reduce information access costs, releasing their potential for chronic disease management solutions.

QR Codes + Education: Unleashing Interactive Teaching Potential
QR codes transform information delivery from one-way communication to interactive engagement. At Guangdong Meteorological Technology Training Center, Chen Dekang developed a QR code management system without IT support, achieving:
- Training session check-ins via WeChat scans
- Event registration through forms collecting names, contacts, and locations
- Anti-fraud measures using timestamped geotagged selfies
As described in Design and Implementation of QR Code Management System for Meteorological Training, this system automates attendance tracking while enabling mobile learning resource management.
Professor Cheng Xingguo from Guizhou Minzu University innovated a mobile classroom interaction method using QR codes for pre-class preparation monitoring. By uploading next-day materials to QR codes and tracking scan statistics, educators gain real-time insights into student engagement through the workbench.
Supported by university teaching reform projects, this approach enhances resource accessibility and fosters self-directed learning capabilities.
