But by 2012...
Anybody paying by debit card will be using Visa anyway.
At the rate banks are dumping Maestro, there won't be any option.
HSBC dropped Maestro in favour of Visa late last year. Reason given when my wife asked why: "some countries don't accept Maestro, so holidaymakers can find themselves without card facilities".
NatWest are currently rolling out Visa and kicking Maestro into touch. Reason given when I asked why: "some countries don't accept Maestro, so holidaymakers can find themselves without card facilities".
Visa is being forced into a monopoly position by this (independant) strategy, not really their fault that the 2012 shop managers are getting one thing properly ready.
