At this time, you can only use your UnionPay debit or credit card to book reservations on Airbnb that are less than 28 nights long. You also need to be sure that online transactions are enabled on your card—please contact UnionPay if you haven’t already turned this on.
Once you select UnionPay as your payment method and are ready to book, click Book Now. You’ll receive an SMS with a one-time password. Once you get it, enter the code into the keypad, keeping in mind that the numbers on the keypad will change after every number you enter.
