The Polymer Code Collection is a web-based payment system that allows users to make payments using their AliPay account. To use the service, customers can log into their AliPay account and select "Polymer Code Collection" as the payment option. Once they have done so, they will be asked to enter the amount of money they wish to pay in order for the transaction to be completed. After confirming this information, customers will then receive a unique code which can then be used at any participating retailer or vendor in order to complete their purchase.
