Hotels – Help on Booking.com – Travel Stack Exchange

I recently booked a hotel with my friends card via booking.com. She will not be going to the hotel at check-in time and I know that booking.com does not charge your card immediately. They say it's just a way to secure your room.

Can I use my own debit card at check-in to pay the full amount? If this is the case, will booking.com still bill his card while his card is registered with booking.com?
