In the UK although MasterCard and Visa are very well known and widely accepted, for historic reasons most debit cards (linked to current accounts) tend to be Visa - around 90% of them. The reason for this is back in 2006ish when ‘Switch’, a UK debit scheme run by NatWest and HSBC, merged with Maestro (part of MasterCard) and then HSBC and NatWest decided to issue Visa debit cards. I was looking after current accounts at Norwich and Peterborough Building Society at the time and did the same - MasterCard were really not at the party. However, things change and MasterCard are keen to be a bigger part of the UK debit landscape and so they are being very helpful and innovative. That’s part of the reason why your Mondo :mondo: (or M…) current accounts will be MasterCard debit!
