By the name and phone number registered in the system, the sales counter notices it is a foreign passenger and then checks availability of the request; if there is an empty place, an email indicating the payment must be done by PayPal is sent to the passenger. In case of no availability, another hotel is suggested in the email in addition to PayPal payment. In the end, the payment procedure is checked with the passenger by phone or email; if it has been done, the voucher will be sent to the passenger.
