Designed and developed a tracking system using QR codes. This helps to identify
and allow entry only for authorised vehicles. It also logs vehicle movement details.


Industrial facilities handling a large flow of trucks for transporting goods need automated truck authentication system to prevent unauthorized entry and to speed up the gate scrutiny time requirement.

The Client

Our client is one of the leading Agri food companies in Ghana with customers all over the world.

The Challenge

The client sources goods through their farmer network and processes them before exporting them to international markets. The client has warehouses in Ghana for the storage and distribution of these goods. Initially the details of vendor trucks entering and exiting the client’s warehouses were captured manually and logged into their system. As the logging process was manual, it is prone to errors with some loopholes which leave scope for fraud. The client wanted to check this and regulate it by digitizing the entire process.

The Solution

We had come up with a detailed design for digitizing the logging of truck movement. The challenge here was to restrict the entry of unauthorized trucks.

After some brainstorming, we zeroed in on using QR codes to identify each truck. We developed an application that captures and stores truck details like vendor name, vehicle number, driver name, and other information and maps it to a QR code. Each truck is given a unique QR code that is linked to its corresponding truck details. This code is printed and stuck on the truck.

We identified a vendor to make QR code stickers that cannot be tampered with. Damaged or tampered stickers need to be replaced after approval from admin.

We also developed a mobile app that scans QR code on the truck and checks it authenticity. Entry of unauthorized trucks could thus be restricted.
