Yep - that's exactly right. We use the confirmation SMSs from your bank ... to determine how much you've spent and calculate the 'digital spare change'.
Please explain further.
Do you have access to read the SMS messages that the bank sends me when a transaction goes through my account?
If I spend R95 what guarantee do I have that only R100 will come out of my account? What measures are in place to prevent "accidental" deductions of larger amounts?
And, in the above example, is the extra R5 that you deduct treated as a second transaction by the bank, thereby triggering additional transaction fees?
