You know, most people here in Germany do indeed prefer cash. And for those who don't (like me), Apple Pay is extremely limited and mostly works with credit cards only. It doesn't even allow PayPal.
And who tf pays for groceries with their credit cards? I never head from anyone here besides Tourists pay with their credit cards for groceries or gasoline.
If we use electronic payments, we expect it to be withdrawn from our bank accounts the next day, not accumulate on a credit card waiting to be paid next month with fees.
With my android device however, I can use Google Pay or Paypal with NFC and choose where they payment comes from.... girocard, credit card, paypal credit...
Some banks do promise to introduce Apple Pay in 2020, but until then, let's see. And even though iPhones are quite popular here in Germany, Apple Pay is not interesting to most because it's so limited here.
