The value lies in being able to create a permanent ledger that cannot be changed for your products that anyone can access. For example if this was around during the time of Da Vinci, he could have recorded his paintings onto the blockchain and attached a QR code to the back of them. Then today we would be able to scan that QR and trace the painting back to him. This is a huge deal as some art experts claim almost 50% of paintings in museums are fake.
Another use case would be for cars. Each car could have a QR code attached and every time a mechanic does a repair they could add that service record to the car's ledger, creating permanent service records (a big issue faced with buying used cars is a lack of service records).
The use cases are endless. And when we do take it off of the testnet and onto the actual blockchain we want to bring the cost of gas down significantly so that it will almost be like paying nothing. We are adding the explanation to our page very soon! And thanks I just posted on your website!
