Expiry Mitra uses AI and blockchain to check medicine expiry from images and logs the data on opBNB, helping users avoid expired or fake medicines.
Counterfeit and expired medicines are a silent threat to public health. In many regions, users unknowingly consume unsafe drugs due to faded or unclear expiry labels. There is no simple, transparent system to verify medicine authenticity before consumption.
Expiry Mitra is an AI-powered tool that lets users scan medicine strips to detect expiry and manufacturing dates using OCR. It instantly checks if the medicine is expired and records verified data on the opBNB blockchain, ensuring the result is transparent and tamper-proof.
Storing data on opBNB ensures:
Tamper-proof verification records
Transparent logs accessible to users and regulators
Trusted, decentralized audit trail of medicines
Upload photo of medicine strip
