Bernd (DE - Hamburg)🇩🇪 Why? It’s the same when we changes from the local payment system “PIN” to Maestro. Now it will be a change from Maestro to Mastercard Debit.
Most likely, the banks will do the same as at that time, when your card expires, you’ll get a new card with both schemes, and when everyone has switched, only new cards with Maestro.
What really is a problem is that some countries still have their own local payment system and stick to that.
