Have manual oversight

An insurance company submitted a regular file for GIRO deduction from their customer accounts. Due to a "file format error", the amount deducted was 100 times of the expected amount. The decimal point was overlooked.

I suggest that the company requesting for GIRO deduction should submit a control total of the amount to be deducted. This will ensure that they have checked the transactions.

If the control total shows an unusually large amount, it would have been noticed by the control staff.

We cannot assume that computer systems will work properly. It is dangerous to rely on computer processing without manual oversight.
