I have not heard anyone mention Alipay and WeChat pay as a point of difference.
To me, these are epayment giants just dipping their toes in the Aust environ. The fact the Smartpay have already integrated gives me confidence that they are in the know.
Pre-COVID, Alipay and WeChat pay was beginning to gain traction. Take a walk around Chinatown and every second retailer had a terminal on their counter. Granted, COVID has sent a fair few Chinese students back home so there might not be as many users at present, but when the borders reopen, who's to say they won't return, with their families in tow?
WeChat pay in particular do a lot of viral marketing on their platform creating their own markets and sales funnels. Social media + payments all-in-one.
