In the medical field, Smart packaging offers multiple benefits. It enables batch management by embedding RFID tags or QR codes, allowing for precise tracking of drug batches with details like production time and location. For supply chain transparency, integrated sensors monitor temperature and humidity during transport, sending alerts if conditions deviate. In terms of security, it uses diverse anti - counterfeiting methods including encrypted QR codes and blockchain - based verification, along with anti - tampering designs that leave traces and record opening details when packages are illegally accessed, especially important for controlled drugs.
