This article is a little dated but I found the conclusion in German distrust of cashless payments interesting.

Culture plays a role, too. Digitally sophisticated Scandinavians may be comfortable buying groceries on their smartphones but a deep-rooted aversion to being tracked—a scar left by the Stasi—lies behind German distrust. A recent survey by PWC revealed that two in five Germans don’t use mobile payments because of concerns about data security (and nearly nine in ten worry about it). When the German finance ministry recently proposed capping cash payments at €5,000, as in some other countries, Bild, a daily newspaper, organised a reader protest.

Isn't Berlin quite different to other parts of Germany? When I was in Munich last year they seemed to have a more progressive view.

On another note, as a German, I think the acceptability of mobile payments is slowly but surely increasing. In my town, all of the shops and restaurants I use take NFC payments and I pay with Apple Pay multiple times a day.

An exception are typical money laundering and tax evasion businesses such as many Vietnamese restaurants.
