Programmable Stickers to Monitor Perishable Goods using Blockchain

The healthcare and medicine production goals are to provide quality goods and prevent any counterfeit drugs with the help of the supply chain. The medicine tends to deteriorate its chemical properties when it is exposed to extremely high temperatures or low temperatures beyond its specified optimum level. The optimum temperature should be controlled even when it is subjected to high or low temperatures. When the medicine is exported, the entire flow process from the manufacturer to the customer should be monitored to meet the goals. The principal motive was to solve the issue of the transport of putrescible goods such as medicines, vaccines food products, etc. liable to the changes in the environment which might affect their chemical composition. An RFID tag is employed to track the temperature of the package, during transportation and storage. The components involved are a passive High-Frequency Radio Frequency Identification (HF-RFID) tag kept within the package to read the surrounding temperature, an RFID reader which gets updated with the readings from the tag, a smart device, here, a phone, to access the information graphically via an application and a temperature adjusting installation inside the containment box. Another biggest challenge is to prevent counterfeit drugs. Blockchain technology is proposed to use in the supply chain to prevent data manipulation and data breaching. The blockchain platform along with the Internet of Things (IoT) framework is used to store and secure data at the end of each process in the supply chain and provided to the customers to view.
