Integrating physical devices with IOTA — The Track&Trace App.The 16th part in a series of beginner tutorials on integrating physical devices with the IOTA protocol.Introduction
This is the 16th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will be using a bar-code scanner together with our own web app. to simulate using the IOTA tangle to create a tamper proof audit trail of events in a typical supply chain with multiple actors.
You will also have the option of typing in bar-code ID’s manually in case you don’t already have access to a bar-code scanner.
In my personal opinion, supply chain management is probably one of the first areas where we will see real industry adoption of DLT technology. The main reason being that this technology has the potential of solving so many of the problems this industry is struggling with today, problems such as lack of transparency, tractability and trust. I would even go as far as suggesting that DLT technology will be at the core all supply chain interactions in the future.
The Use Case
Lately our trusted hotel owner have noticed a problem with degrading quality of seafood products he gets from his friend Bob the fisherman, who is located in a small fishing village up north. He suspects that the problem is not related to Bob or the product itself, but rather delay in the supply chain from when the product was shipped to when it arrives at his hotel. As there are multiple actors involved in the shipment, it is not clear who is responsible for the delay and who should give him a refund for the faulty product. When he tries to address the problem with the various actors in his supply chain, they basically blame each other and no one takes responsibility. He even suspect that some of them manipulate the paperwork that comes with the shipment to avoid taking responsibility.
