Abstract: A computer-based method for making an in-game purchase from an independent electronic data processing unit. The computer-based method may comprise the steps of: providing a server application configured to run on a server, a first application configured to run on a first electronic data processing unit, and a second application configured to run on a second electronic data processing unit. The first application and the second application may be configured to access the server application online. The first electronic data processing unit may be configured to allow a user to play an online game. The second application preferably allows the user to purchase an in-game feature for the first application by making one or more payments in the second application, and the user preferably sends a payment through the second application. The server application preferably receives the payment from the user, and the second application may be an in-game payment application.

Abstract: A computer-based method for linking user account information for making future payments. The method may comprise the steps of: providing an application and a server application; displaying the application through a display screen and prompting the user to input a phone number of a mobile computing device into the application via an input device; receiving the phone number from the user and sending the phone number to the server application; generating and transmitting a text message with a uniform resource locator (URL) link from the server application to the mobile computing device based on the phone number; prompting the user to open the URL link; opening a webpage in a web browser in the mobile computing device when the user opens the URL link; prompting the user to input user account information into the webpage; receiving the user account information from the user; and saving the user account information in the server.

Abstract: A computer-based method for sorting payment systems. The computer-based method may comprise the steps of: providing an electronic data processing unit; obtaining one or more parameters of a user by said one or more applications; creating one or more payment systems groups; prioritizing the payment systems groups by the application; populating at least one of the payment systems groups with one or more payment systems based upon the parameters; sorting the payment systems within one the payment systems groups to create a sorted payment system; adding the sorted payment systems to a list; and displaying the list to the user.
