S-SHOP@TMIT
Advantage
1. When I first time to use the interface, I don’t have miss understaning of how to use the app.
2. It have good color design and clean layout.
3. It have QR cord function to screen the QR cord to know what it does.
Disadvantage
1. when the shop doesn’t have the product in the unmanned shop, the user also can buy using the app.
The size of elements reflect their importance becaucse the money of the product the text is very big.
Sketchstorming – Using diagrams to express solution
The problem with the app is when the shop doesn’t have the product in the unmanned shop, the user also can buy using the app. I think it can create a function to check the e-shop have this product or not in database, if the e-shop don’t have this product, app will show the product is sold out.
