Abstract: A wearable device, e.g., a smart watch, may be connected to a communication device, such as a mobile smart phone, via Bluetooth or other Near Field Communication (NFC). In particular, the wearable device may have a touch screen that may serve as an extended display and/or user input device of the communication device. For example, a user may receive payment related notifications on the wearable device. The user also may operate the wearable device to make and/or receive payments, view transaction history, view and/or accept offers from nearby merchants, view and/or check in to nearby stores and etc. Further, the wearable device also may allow the user to make payment transactions in extreme environments not suitable for the communication device, such as under water.

Abstract: In an embodiment, a system includes a processor coupled with a data store, the at least one processor configured to: receive a client product version number from a client device; identify a differential bundle based on a difference between the client product version number and a current product version number, wherein the differential bundle comprises a set of bytewise differences between an executable client product binary file associated with the client product version number and a executable current product binary file associated with the current product version number; determine whether the differential bundle is available in the data store; retrieve the differential bundle from the data store in response to determining that the differential bundle is available in the data store; produce the differential bundle in response to determining that the differential bundle is not available in the data store; and send the differential bundle to the client device.
