Abstract: Dynamically generated quick response (QR) codes are used for secure communication to/from mobile devices. In one example, a QR code identifies a product or service selected by a user using a mobile device. The mobile device generates the QR code identifying the user's selection, and displays the QR code for reading by a retail kiosk. The retail kiosk, such as movie-rental kiosk, extracts the product or service selection encoded in QR code and provides the identified product or service to the user. The QR code can additionally identify a user account, such that payment for the product or service is automatically charged to the account identified from the QR code. In another example, the QR code is used to transfer money and/or credits between a user and a retailer, or between two users.

Abstract: Systems and methods for determining an action plan with respect to a returned device are disclosed. In some implementations, a computer receives an identifier of a returned device being processed by a replacement center. The computer provides the identifier of the returned device to a data repository. The computer receives, from the data repository, in response to the identifier of the returned device, data related to the returned device. The computer calculates a device retirement metric based on the data related to the returned device received from the data repository. The computer determines, based on the device retirement metric, an action plan to take with respect to the returned device. The computer provides an indication of the action plan with respect to the returned device.
