Do third parties, whom we pay via paypal, get to know our card's number? I ask this because I made three transactions 2 days ago through paypal, and they billed me a few euros as was the deal. But then I found out that they might actually be a "scam" site. So I must know if they can access my credit card's number - since I payd through paypal - to go to change my credit card if so. On the meanwhile I cancelled the transactions with that site through paypal settings. Thank you very much.
