OK, this is what someone else came up with on another board...correct it if it's wrong:
It would cost a u.s. resident $35 per $1000 atm withdrawl - 2% plus $15 per withdrawl - plus whatever the atm fees are plus 3% interest annually. that means someone who gets paid $50,000 a year through okpay would pay $3250 annually in fees including the 2% plus $15 per withdrawl and annual interest where it would have cost around $290 by epassporte.

2% atm fees on $50,000 is $1000
average of 1000 per withdrawl means 50 withdrawls total at $15 each is $750
that's $1,750 for withdrawl fees
3% interest of $50,000 is $1500
$1,750 withdrawl fees plus $1500 interest is $3,250.
