I checked out the site and where there use to be listings of merchants and
banks, there are none.
There is a blurb about a successful pilot.
I knew at one time they had Mark Twain Bank signed up. The last time I
looked it was just non-US banks.
Mark Twain probably got gobbled up in a merger or something.
I've heard mumblings that US banks are just sitting quietly until the patent
runs out. Supposedly they are
doing the same Smart Card Technology.
