So, I just opened my e-commerce visa/mastercard statement and read this:
…also effective October 2009, there will be separate line items on your merchant statement for the Visa Misuse of Authorization Service Fee… will be assessed on authorizations that are approved but never settled with your daily batch, as these can adversely impact cardholder’s open-to-buy, leading to increases declines and confusion at the point of sale.
Well, duh! The clear solution is to charge me a fee - much better than providing a means by which to remove canceled authorizations.
At least my merchant service is passing them along to me “with no markup.”
