Not German and I don't think there was ever such hyperinflation here, but same reasons basically. - fast enough - no problems with failing electronic payments of all kinds - more places where it works (electronic payment systems can indeed be an extra cost which matters for small businesses) - cash doesn't break (cards do) - still easier to transfer directly between people - pretty private
