In more detail
A chargeback is the reversal of a card payment through the bank; in crypto exchange it is a risk for the seller, since the buyer can reverse the payment after receiving coins (which cannot be returned). Because of this, exchangers treat card directions more strictly and sometimes ask for confirmations. An honest user should pay from their own card and keep receipts.
