Merchants in Europe got new payment processing systems to comply with new EU rules in late 2019 / early 2020 so the terminals were upgraded/replaced just before the pandemic hit. I suppose with the upgrade the logic of DCC and the customer facing interfaces also got redesigned. Since there is a massive uptick in contactless payment (card wave, smart devices, qr code scan etc) DCC is also moving with the times and adapting to be in that space too
