Visa, Mastercard, Amex, Diners market share against each other in Europe 2015-2022

When comparing the four big international card brands available, the importance of Visa in Europe declined between 2021 and 2020 in favor of Mastercard. This has been an ongoing trend for the payment brand, as its market share declined by 10 percentage points between 2015 and 2020. Note, however, that this market share is solely based on the number of purchase transactions done with Visa, MasterCard, American Express or Diners Club only - as domestic solutions were not included. This way, the source is effectively saying that out of the global network cards Visa ranks higher than Mastercard. It does not mention, however, how these purchase transaction compares against payments outside of these four brands. This is an important observation, as some domestic payment solutions - such as Italy's Bancomat or Germany's Girocard - have a much higher market share than either Visa or Mastercard.
