Como é que se diz isto em Inglês (EUA)? 체크카드는 신용카드하고는 달리 가승인(prior authorization)이 되지않고 바로 결제되는 거 알고 계시죠?
제가 호텔에 도착했을 때 결제된 거 취소해주시나요?

I'm going to loosely translate it to English to make it sound better.

"You know that check cards/debit cards are different from credit cards because they don't need/require prior authorization of payments, right? Check cards/debit cards withdraw money directly from your checking account.

Could you please cancel the payment made when I first arrived at the hotel?"

------
We call "check cards" debit cards in the US.

And I'm not sure if you're using the first part in the same context at the hotel, but I personally would not say that to a hotel employee.

The first section would be more like a bank employee telling a customer how debit cards and credit cards work. It would seem kind of rude to explain that to a hotel employee.
