QR Codes in Supply Chain Tracking
Research Guide
What is QR Codes in Supply Chain Tracking?
QR Codes in Supply Chain Tracking use scannable 2D barcodes to enable real-time product traceability, inventory management, and anti-counterfeiting across logistics networks.
Research integrates QR codes with IoT, RFID, and blockchain for tracking goods from production to delivery. Studies focus on food, textile, and meat supply chains, with over 50 papers since 2012. Key works include Li et al. (2017, 176 citations) on IoT-based food tracing and Qian et al. (2017, 26 citations) on QR readability optimization.
Why It Matters
QR codes improve supply chain transparency by enabling consumers to scan products for origin and safety data, reducing food fraud incidents (Li et al., 2017; Dey et al., 2021). In textiles, secured QR tags combat counterfeiting, boosting economic growth in developing countries (Agrawal et al., 2018). Integration with blockchain ensures tamper-proof records, as shown in FoodSQRBlock systems handling outbreaks efficiently (Dey et al., 2020).
Key Research Challenges
QR Readability in Motion
Scanning QR codes during high-speed movement in logistics degrades accuracy due to blur and vibration. Qian et al. (2017) used response surface methodology to optimize parameters, achieving better readability (26 citations). Challenges persist in dynamic environments like conveyor belts.
Integration with Legacy Systems
Combining QR codes with existing RFID and ERP systems requires standardized protocols. Shamsuzzoha et al. (2012) evaluated tracking performance, highlighting interoperability gaps (63 citations). Real-time data synchronization remains problematic in global chains.
Scalability and Security
Large-scale deployment faces data overload and tampering risks without encryption. Agrawal et al. (2018) proposed secured tags for textiles (52 citations), while Dey et al. (2021) added blockchain for food chains (16 citations). Privacy in IoT-linked QR systems needs further addressing.
