You travel to another city and rent a car at the airport using your credit card. then you check into your hotel using the same card. since both merchants have no way to know what your final bill will be, they do not charge your card that day. but in the evening, you go to dinner at a restaurant, and when you use the same card to pay the bill, you are told that they cannot accept your card. what has probably happened? a. someone has stolen your card number.
b. your most recent payment has not reached the issuer.
c. your card has been "blocked" by both the rental company and the hotel.
d. the restaurant only accepts debit cards.

The correct answer is C) Your card has been "blocked" by both the rental company and the hotel.

What has probably happened was that your card has been "blocked" by both the rental company and the hotel.

To prevent frauds, banks sometimes block credit cards when they detect unusual purchases in order to protect the client and the bank. As the hotel bill and the rented car bill are open, the bank needs confirmation of the part of the client to allow it to continue to use the credit card in other establishments. That was the case with the restaurant. Probably, the credit line of the client has a limit and until final charges of the hotel and car rental are made, the bank will clear the card.
