P.S.I

P.S.I is a system of secured package, adaptable to every type of contents, light, and at a reduced price, which allows the user to follow-up the packet along its way.

One has to note that the services of delivery are not 100% reliable. Indeed, the loss of packets, without counting the deterioration, is a disturbing phenomenon: 1.5 million objects disappeared in La Poste per year, which means 1 package every 25 seconds! For individuals, it can represent a simple contrariety. Nevertheless these losses are equivalent to a 5% loss of turnover for French SME (SMALL AND MEDIUM-SIZED ENTERPRISE). Thus, this observation leads us to the question: How to detect the possible violation of packets (parcel, letters, etc.) during their distribution, in order to insure the quality and the reliability of the service to the customer? That’s why, we had to realize a system of packaging, secured by the RFID technology, assuring at the same time integrity and traceability of the packet all along the distribution chain.

The analysis of the existing helped us to bring new possibilities to our system. The State of the Art allowed us to know the technical and functional requirements that our system will have to respect so that it can be integrated into its environment in an effective way.

For this project, we realized a system of secured package, adaptable to every type of contents, light, and at a reduced price, which allows the user to follow-up the packet along its way. The RFID label, or tag, is connected to a circuit covering the entire packet. In case of unauthorized opening, and close to an antenna, the state of the package, opened or closed, is read via the tag, registered in a database, and an alert is sent to the smartphone’s user. Furthermore our application allows the detection of the packet’s disappearance, sending an alert to the smartphone too. It is as well possible for the user to scan the tag RFID via a NFC-enabled smartphone to know the state. Thus, our project can be divided into three main parts: the UHF communication between the RFID tag and the antenna, the HF communication between the RFID tag and the NFC-enabled smartphone, and the user interface created for that purpose. These three elements are necessary for the smooth running of our system.
