Airline Miles Card Do You Have To Have A Separate Frequent Flyer Miles Card For Each Airline Or Can You Choose Just One For All?

Do you have to have a separate frequent flyer miles card for each airline or can you choose just one for all? - airline miles card

I have a loyalty card for Germany, but I can use the card to fly a different airline? Or you need a separate card to another airline? Does this mean that I have a couple of miles on each card instead of a large lump sum be?
