Financial Performance Outcomes of DownsizingIntegrative Analysis of QR Codes for Food Supply Chain Integrity

Quick response (QR) codes are increasingly used on food packaging to provide consumers with accessible digital information. Their small size, ease of use, and ability to link to dynamic content make them promising tools for enhancing food authentication and supply chain integrity. However, effective implementation depends not only on adoption by supply chain actors but also on consumer engagement and acceptance, as various factors influence their use. Understanding stakeholders’ perceptions and consumers’ behavioral intentions is therefore essential to promote wider adoption. This thesis highlights the role of QR codes in strengthening food supply chain integrity through approaches, including literature review, interviews, surveys, and meta-analysis, which offer strategic insights for improving adoption. Additionally, the thesis proposes a novel spatial-temporal method for detecting food fraud based on consumer QR code scanning data, providing new opportunities to enhance authenticity monitoring and combat food fraud effectively.
