Smart packaging, also known as "smart labels", is a way to embed information about a product into its packaging using QR codes, RFID tags, or other digital technologies.

Blockchain can be used to create a secure and transparent record of this information, making it easy to track and verify the authenticity of products.

Smart packaging can also be used to monitor the condition of products during transport and storage, helping to ensure that they are safe and fresh when they reach the consumer.

Additionally, smart packaging can be used to provide consumers with more information about the product, such as its ingredients, nutritional value, or supply chain details.
