Alipay Hong Kong is the first non-RMB version of Alipay's mobile phone application, which was listed in May 20 17 and supervised by the Hong Kong Monetary Authority. Huo Jianning, Chairman of Alipay Hong Kong Board of Directors, said that Alipay Hong Kong aims to cover the whole country within this year. Since March, its business will expand from Hongkong to the mainland cities in Guangdong-Hong Kong-Macao Greater Bay Area, covering catering, tourism, medical care, transportation and other aspects. Hundreds of thousands of stores in mainland Greater Bay Area will accept users to pay with Alipay. However, the following points should be noted: 1. The scan code payment of Alipay in Hong Kong is the same as that in the Mainland. Merchants can pay by scanning the QR code. 2. Alipay in Hong Kong uses Hong Kong dollars for settlement, and users need to bind credit cards in Hong Kong for payment. 3, local online banking, to the convenience store to recharge the balance. The balance can be withdrawn, but real-name authentication is required. If you use Mainland Alipay to transfer money to Mainland Alipay in Hong Kong, the transfer steps are as follows: 1, log in to Alipay 2, click "Transfer" operation 3, and enter the other party's account to pay 4. The transfer is successful.
