Transmission of objects
Before taking a parcel, the courier or transporter has to check that everything is legal. If there are illegal items, he does not have to take the parcel. In some countries, the legislation can allow a person-to-person delivery. In other countries, the legislation requires to be a professional service and even buy special equipment to check the parcel for instance in special checkpoints. The project is for responsible and authorized services.
Before transmitting the parcel, the sender can take a picture and send a hash of the picture to the Blockchain, which we use in that case as a proven timestamp. In case of dispute, the sender can prove that the photo was taken before the transmission date. When taking the parcel, the courier can see this photo and check that it corresponds to the content of the parcel.
Before closing the parcel, sender can add connected devices with sensors into the parcel.
Each delivery is identified by its delivery smart contract address on the Blockchain. A QR code is printed on stickers pasted on the parcel. The sender and the courier can close the parcel using smart stickers used for traceability, VOID tampering, sealing and authentication.
We prove the transmission of objects with the double signature of the sender and the courier. When the sender transmits a parcel to a courier, both sign the transmission using delivery smart contract methods with their mobile application. These methods automatically lock the fee and deposits in the smart contract until the delivery of the parcel or the predefined contract end date. It will take less than one minute to complete the proof of transmission on the Blockchain.
Delivery and reception of objects
The reception is established during the handover of the parcel after the double signature of the courier and the receiver defined in the delivery smart contract. When the courier transmits the parcel to the receiver, both sign the transmission using delivery smart contract methods with their mobile application. This automatically unlocks the fee and deposit from the delivery smart contract. It will take less than one minute to complete the proof of transmission on the Blockchain.
The delivery is possible to a private postbox and without the attendance of the receiver. In that case, the receiver has to be confident and/or the postbox smart and connected to allow unlocking fee and deposit.
The parcel with its deposit can also be transferred to a local public postbox. In particular, this is the case if the courier cannot deliver the parcel to the receiver.
Lastly, the courier can transfer the parcel to another courier using the same process than for the transmission from the sender.
