Unfortunately, this is for Sainsbury’s to resolve, the company that didn’t get contactless until last Christmas.
- I just checked the application language label is correct (present in the correct place, set to English) on the Monzo card, and it is, at least on my recently-issued current account card.
- The fee notification is something these ATM operators always display for the MasterCard AID. It has nothing to do with BIN range, or if the card is foreign, or anything like that. Any MasterCard transaction will create this message. Most British banks are members of LINK and their debit cards have two AIDs - one of the major global networks like Visa or MasterCard, and LINK. ATMs in the UK prefer LINK and auto-select it where available. Monzo doesn’t have LINK, so the MasterCard AID gets selected and that’s a message the ATM operator shows for any MasterCard transaction.
2a. Worth noting on its own just how inaccurate that can be - every American Express-issued card, worldwide, also has the LINK AID. These will have cash advance and possibly foreign transaction fees. Network doesn’t prove fee or lack thereof.
