The Cardassians are said to use leks.
The Ferengi use gold pressed latinium, which seems to be the US dollar of the Alpha Quadrant pretty much.
The Federation somehow doesn't have any currency system it somehow being "primitive"
I've long thought that when Picard snootily told the 20th century people that 24th century people don't use money, he meant 24th century Starfleet
people. But this is obviously ridiculous, since in "Encounter at Farpoint" Beverly is seen buying
a bolt of cloth and telling the merchant to charge it to her account. That presupposes that there is some way for her to draw on whatever currency units she needs to meet the price asked by the merchant.
The TOS series used "credits" which were apparently real, whether in physical form or some kind of virtual money. But I say "real" because if you don't have enough credits in your account (or in your wallet), you don't get whatever it is you wanted to buy.
Sure, Ben Sisko's father runs a restaurant, partly because he enjoys providing real food to people instead of replicated crap. But it would be insane of him to not try to make a profit. Since he's a civilian, he obviously uses money of some sort.
When Picard and Ro Laren were doing their undercover thing, Ro was pretending to be a prostitute. She told Picard that they had to make it look to any observers that they were negotiating her price - which would presumably be paid in strips of gold-pressed latinum, since this was not only a civilian situation, but actually an underground situation.
DS9 evidently uses gold-pressed latinum as the currency of choice on the "frontier", much as the Wild West used gold and silver. But that's not to say the more "civilized" parts of the Federation would use this; they'd likely do the equivalent of online banking.
