It looks like Amazon liked barcode scanning with a mobile device idea so much, they filed a patent on it.
In my opinion, I think they should find out who has the patent that allows clicking on a barcode and buying with one-click patent. That would be valuable for an online retailer.
The physical world gets connected with the electronic one and mobile marketing is born.
I still don't think price comparison using a mobile device will gain acceptance like many are predicting.
Clicking on a barcode for more information on a product would be welcomed by brands. Instead of price comparison, why not make the product interactive.
