If a guest makes a booking for himself using his credit card, he needs to show the credit card used for booking at the time of check-in.
If a booking is made using someone else’s credit card then a copy of the credit card along with a no-objection letter signed by the owner of the card has to be produced at the time of check-in. The letter should contain all the details (name of guests, type of room booked, name of the property, etc.) and the CVV no. should be hidden in the carbon copy of the credit card.
