1 Currency conversion fees may apply for the buyer when paying in a different currency. For sellers, transaction fees on QR code payments are temporarily waived until 31 December, 2020, to help businesses impacted by COVID-19. After that, you’ll pay a fee of 1.20% + $0.80 HKD per domestic transaction when your customers with PayPal Hong Kong accounts pay you. Other fees for using the PayPal Services may apply, including commercial payment fees for receiving international payments – see fees. PayPal QR code payment functionality does not benefit from PayPal Seller Protection Policy.
