小伙伴代付小幫手 is a Chrome add-on developed by Taocarts. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This add-on allows customers to use the proxy payment function without having to open the Princess Payment website.

When customers make a purchase and confirm the order, they can choose to use a friend's payment. Upon entering the payment page, the 小伙伴代付小幫手 add-on will automatically pop up. Customers can log in or be redirected to the official website for registration. If a customer is already logged in on the official website, they will be automatically logged in and their information will be displayed in the add-on pop-up.

Customers can use the prompts at the bottom of the add-on pop-up to proceed with the proxy payment. Alternatively, they can click on the Princess Payment icon in the top right corner of the browser to view the process and usage instructions.
