Only since the EU limited the fees. Until 2016, neither ALDI nor LIDL nor REWE nor PENNY nor Edeka nor Coop supported it.

I know it's nitpicking but Rewe has accepted credit cards since 2007.

Some REWEs have, but not all. There's still some where I live that don't. (REWE eG is a cooperative, so it's all a bit more complicated)

Basically there is Rewe Dortmund (with stores across NRW) and Rewe anywhere else (including NRW). The latter requires credit card acceptance for all Rewe-branded stores. If a store does not have that, an email to Cologne usually changes it.

There's also Rewe and Coop (Sky, Plaza, etc) in Schleswig-Holstein, which have merged now, but offer different amounts of credit card acceptance.

And members of both have reservations against MasterCard and VISA, due to what happened with Rossmann a few years ago (Rossmann sold cuban cigars, as punishment MasterCard, VISA and PayPal seized Rossmanns funds and suspended all payments), but as EC was also bought by MasterCard and merged with the Maestro brand, currently there's no option but to continue on.

Personally, as member of both the REWE eG and coop eG, I'd support a move away from CC to any national or EU based payment system as soon as possible.

I know that there are some reservations but the rule the cooperative (including SH) decided as binding still stands. You are of course free to lobby internally for change.

Rewe has a fairly complicated legal structure, I'm not sure which you are a member of. There is no single "Rewe eG" which you can just buy into, especially not if you don't happen to own supermarkets.

EC was not bought by MasterCard, the brand was always owned by them (though there have been various mergers). The system behind those cards was not merged with Maestro (which is a different system) but merely rebranded as Girocard, an independent scheme by the German banks. It works without any reliance on MasterCard.

I'm personally not sure either. Originally my entire family was just a member of the coop eG, but when they started to merge with REWE eG in the past months the coop eG offered an option to invest additional money into the REWE eG (at better than usual terms). So we did.

So now we have some stores that have just been rebranded REWE, some still branded Sky, operating with the same mix of REWE and Sky products, and some accepting CCs, some not.

In marketing, EC stopped being the main brand, though, and MasterCard provides their EC cards under the "Maestro" brand within of Germany, although they are not operating over the Maestro network, or in any way compatible with it. Take any recent EC card, it'll work only via the EC system, say Girocard Electronic Cash on the back, and Maestro on the front, but doesn't actually have any relation to the Maestro system. That's what I was referring to with the rebranding.
