Walmart, the largest retail chain, has developed a new design that is able to maintain product quality during transportation. This invention was named «Smart parcels».
The main feature of smart parcels — the presence of a device that displays the address of the seller and the recipient, the contents of the parcel, its geographical position, temperature and humidity of the external environment. All data is entered into the blockchain, so the risk of changing information is reduced to zero.
An application to the US Patent Office indicated that online sellers are increasingly faced with the challenge of transporting products that spoil quickly. Blockchain technology allows buyers to control the delivery conditions themselves to ensure the reliability of the courier service.
