Abstract: A merchant creates a record with a payment processor. As part of the record, the payment processor records identification codes for one or more merchant operators of the merchant system. The merchant operator, such as a vendor, presents their identification code to a user that desires to purchase a product from the vendor. The user's computing device receives the vendor's identification code, as well as transaction details for the desired purchase transaction. The payment processor receives a request from the user's computing device to process the purchase transaction. Based on the identification code received and the transaction details, the payment processor identifies the merchant record and verifies a financial account for the user. The payment processor provides an authentication to the user computer device, which includes an authorization indicator, such as a vendor password. After the vendor views the authorization indicator, the vendor can provide the product to the user.

Abstract: Some implementations include displaying media content items on a home screen of a computing device. A display order for a list of media content items may be determined based, at least in part, on a predicted likelihood that an individual one of the plurality of media content items will be selected. A home screen of a user interface may be displayed, according to the determined display order, with a list of a plurality of media content items that are available to the computing device.
