便利运小幫手 is a browser add-on that allows customers to conveniently use the proxy payment feature without having to open the convenience shipping website. When customers make a purchase and confirm their order, they can choose to have a friend make the payment on their behalf. Upon reaching the payment page, the 便利运小幫手 add-on will automatically pop up, giving customers the option to log in or redirect to the official website for registration. If customers are already logged in on the official website, they will be automatically logged in through the add-on and their information will be displayed in a pop-up window. Customers can easily make proxy payments by following the instructions provided at the bottom of the add-on pop-up. Additionally, they can access the operating instructions and usage process by clicking on the convenient 便利运小幫手 icon located in the top right corner of the browser.
