I've been able to witness the change over the last 5 years in Germany. While gradual, it has been quite noticeable to see more plastic options become available, and my ATM visits have become less frequent.
It's still a far cry from home (Australia) where I hadn't needed cash on hand in quite a long time, but it in terms of convenience it's not a big deal. it certainly beats France where cheques are still in extremely frequent use vs. wire transfers.
