Abstract
This article discusses the importance of effective communication tools in public health, highlighting innovations like Quick Response (QR) codes and QR wallet reference cards (QR cards) for enhancing outreach and education. QR codes are scannable barcodes that link to digital content. QR cards are compact cards, similar to business cards, with codes that lead to relevant health information. To our knowledge, there is little published literature on using QR codes and cards for public health programs and health communication outside of health care clinics and education settings. The North Carolina Department of Health and Human Services, Division of Public Health, Community and Clinical Connections for Prevention and Health Branch has successfully implemented QR codes in various public health programs, particularly in diabetes management and nutrition, physical activity, and obesity initiatives. Key lessons learned include using reputable QR code generators, ensuring visibility and scanability of the codes, testing links before use, providing clear calls to action, and considering dynamic versus static codes based on needs. QR codes can be leveraged in public health practice for program promotion, evaluation sharing, and community resource accessibility. However, limitations such as smartphone dependency among some populations should be acknowledged. In conclusion, while QR codes are a simple tool, they hold significant potential for improving public health communication. Research on QR code use in public health settings could help inform best practices for public health programs and health promotion across different contexts.
