Create PIN creation/sales module in existing AngularJS app

Create a scratch card, where users can click on a number of squares to win the shown amount if they are all the same. Mockups are enclosed. There is the creation of the cards, and then the user that tries to win. I will share the repo of the existing AngularJS4 project, but you can see the app running (can register and login) at [login to view URL] Once logged in, go to the services on the left navigator menu and scroll to the section called Wallet Services, and PIN Codes is the section to link to. The style of the layout uses the Sing Template ([login to view URL]) so you can pick what elements are best for this app. Flow: In the system there are merchants and users - a merchant creates or imports codes, specifies the currency and the price, and the user then sees them in a list and is able to buy them. Codes can be for external games, websites etc. The payment is via our own wallet api (wallet/transfer), where when someone pays, that currency is transferred from the user to the merchant account. Once the user has purchased, they then appear in a history list. On the merchant side, they appear in a Sold list. The mockup for this is here: For merchants to create codes - [login to view URL] For users to buy codes - [login to view URL] We have created or may need to create the APIs for certain parts, but you can specify what APis you need and work directly with our developers.
