A local Sparkasse has just announced that they'll have a "Sparkasse-Payment-Tag" in April.
Companies and shops are invited to participate. Someone from S-Payment (the main Sparkasse organisation dealing with payment tech) is holding a keynote speech as well. Although "payment" sounds fairly generic, nearly all the information on the leaflet is concerning contactless "Sparkassencard und Kreditkarte", but also "mobiles bezahlen". The event promises to show merchants what's possible now and what's upcoming. Also all participants will get special deals on an "ElectronicCash Paket" (whatever that is).
And yes, on the last page of the leaflet someone is just hovering a phone over a terminal
It's just a >>generic<< phone though!
I do hope if the big push for contactless mobile in Germany is this year, that the big banks in Germany (and Sparkasse as a whole is defo one of them) does a clean sweep. They need merchants, ticket machines, media coverage and exposure. It's in their own interest if they've been developing this Wallet app for Android.
Honestly, I also still think Apple Pay is on the cards for this year. WWDC is the one to look out for.
