My wife was a victim of this antifraud system last month. She went to
a thrice-yearly show where vendors from all over the country sell their
wares. She made two purchases at one booth. The goods were from two
different vendors -based in different states- so were processed as two
transactions. The second one, just a minutes or two after the first,
was denied with a "card cancelled" code. Then automated phone calls
started coming from Visa to our home number. It was quite annoying.
Impressive, but annoying.
