Lately I have been getting some transactions voided for credit card fraud.

The surprising part of these is that where the reversal takes about 2-3 weeks to happen. Considering all the fraud detection mechanisms in place you would think these cc fraud transactions would be detected much earlier.

Is there any verification done by SAS for the Voided Transactions such as credit card fraud, cancelled sale etc or is it simply a matter of trust between merchant and affiliate and there is no verification undertaken.

It would be good to hear what SAS undertakes in regards to voided transactions, if any.
