Abstract: A data processor implemented method for gamification of activity tracking to determine a reward is provided. The method includes obtaining activity tracking information from one or more activity tracking sensors, and comparing one or more associated activity tracking target with the obtained activity tracking information to generate an activity tracking level. The method also includes assessing the activity tracking level for determination of the reward, and interfacing with a payment gateway to make payment to an entity associated with the reward, wherein an amount of the payment is dependent on the reward.

Abstract: A method of providing instructions to a payment device, wherein instructions are generated without requiring data from the payment device, the method comprising: delivering instructions that are part of an ordered sequence of instructions to a payment device; and identifying instructions that should be applied out of sequence without preventing the delivery of subsequent instructions in a sequence. A method of receiving instructions at a payment device and a payment device are also provided.

Abstract: A transaction system for performing transactions with multiple balances within a single transaction. The transaction system comprises a payment device programmed to record multiple balances and a terminal programmed to interact with the payment device in order to complete a transaction by debiting multiple balances of the payment device within a single transaction. A method of transacting with a transaction device, a payment device and a method of providing commodities to a payment device user are also provided.

Abstract: A data processor implemented method for authenticating use of an activity tracking device by a user is provided. The method includes obtaining a plurality of first markers, wherein each of the first markers includes a location and time-stamp of the activity tracking device when the activity tracking device is tracking at least one parameter of the user. The method also includes obtaining a plurality of second markers from a transaction data storage, wherein each of the second markers includes a location and time-stamp of an electronic transaction made by the user using at least one payment device of the user. The method further includes comparing the locations of the plurality of first markers with the locations of the plurality of second markers, and determining, based on the comparison, whether the activity tracking device is regularly in use by the user.
