In Finland the contactless infra is in good shape already. I've been using my Android phone with NFC payments for a few months now and the occasions when I've needed the actual card are getting few and far between. Places where I've paid with contactless include:
- Larger stores
- Small grocery stores
- Kiosks
- Ice cream stalls at a beach
- Store on wheels that once a week visits my inlaws living in a rural area
- A small boat that takes visitors to a small island in front of Helsinki
