There might be something going on with Visa in the UK. I've noticed that all the bank accounts I've had that used Visa for debit cards for many years all seem to have switched to Mastercard recently. Presumably they wouldn't overcome this much inertia unless there was a substantial financial incentive. If card issuers are finding that their costs are too high, chances are payment processors are as well.
Same here, thought I thought was being scammed but everyone else in my family got letters saying that their cards are moving to Mastercard debit in the coming months. I doubt Visa will have much marketshare even in the debit card market by the end of next year.
I think both Visa and Mastercard are increasing their fees like that, but only for payments between the UK and EU (and pretty much simultaneously too - aren't duopolies great?)
They have, but it only applies in the same jurisdiction. So it still applies to intra-UK transactions and to intra-EU transactions. But not to transactions between the two.
