In your case, paying a deposit for a credit card will only freeze the corresponding amount, but the balance on your card will not change. For example, the available amount of a credit card is 30,000 yuan. If the hotel wants to pay the 500 yuan deposit, the hotel will freeze the amount on the card in 500 yuan, and the available amount on the card will become 25,000 yuan. If you spend only 25,000 yuan with this card during your stay, 500 yuan will be unfrozen when you check out.
