Been curious about any experiences trying this recently? I've read that it should work ​​​​​​in theory​​​​​​, but that European merchants have refused to allow folks to try, crying "NO Mastercard!" though these cards have the Maestro symbol on the back. I've never used such a terminal, so is it that they need to activate the transaction, willfully refusing all foreigners?

Most likely that the terminal recoils in horror at the card's BIN, but thought I'd ask. Are local (retail) Maestro debit and global (ATM) Maestro separate entities sharing the same logo?
