Your customer calls the number shown in the internet window and enters the PIN indicated.
2. Payment process
Either the call directly costs the relevant amount for your product (Dropbilling) or your customer will be requested to retain the connection until it is automatically disconnected by mopay.
Again, this also means: 100% coverage, no registration required and the whole process is anonymous, fast, secure and convenient.
3. Payment process complete
When the call and/or the required length of call is confirmed, the payment has been successful and the customer can receive their product. Billing will take place directly via the telephone bill and/or pay-as-you-go credit.
This way of payment is secure as far as i can see, and is a preferable way of payment if you can not use another method.
