First Click test based on scenarios and tasks given to users. Follow-up questions to check if users understand functions, semantic meanings of icons.

For Example, 

1. You are at a supermarket and want to check out and pay for your groceries. Where do you click to show the QR Code for payment? 

1. Where do you click if you want to check out your account balance?

2. You are paying your bill with BoC Pay, but your account does not have a sufficient amount. Where do you click to up the amount?

3. Have you heard of U-plan? If so, where have you heard of that? What do you think it is about?
