QR code payments will allow you to get paid in person with PayPal just by displaying your QR code for customers to scan using their smart phone. You don't need any additional devices.
*Currency conversion fees may apply for the buyer when paying in a different currency. You only pay 1.20% + 0.80 HKD per transaction 80.01 HKD and above, and lower fees for transactions 80.00 HKD and under. Fees are subject to change. PayPal QR code payment functionality does not benefit from PayPal Seller Protection Policy.
