It all depends on what kind of office you will rent a car. The most common option - payment by bank card with the freezing of the deposit for the duration of your use of the machine. There are rental offices, where you can pay cash, while immediately pay the full cost of renting, and your bank card number will be entered into the contract (and, possibly, the passport number). And in some rentals it is possible to rent a car for cash, providing only a driver's license.
