Bei uns wird Kreditkarte der Fremdw?hrung akzeptiert.

Swipe card: pure Chinese saying, no corresponding word-for-word Western language translation.

In the store A signboard can be posted at the door like this:

" Alle Kreditkarte

akzeptiert!"

This already indicates "our shop" and so on, because it is clearly stated:

"Accept

All credit cards"

The original question is the difference between "RMB credit card" and "foreign currency credit card".
