Re: Clarification needed

I think it works like this:

1. User runs the WeChat Pay app, phone displays a secret QR code

2. Merchant scans QR code, sends payment request to AliPay

3. Payment request shows up on user's screen, PIN code needed to confirm transaction

4. If correct PIN code is entered, payment is processed and merchant terminal spits out receipt

I assume the QR code is an OTP used to encode the user's AliPay account number. You can also set a daily or per transaction limit for bank accounts linked to the AliPay account.
