A user is provided with a GUI that may allow the user to change functionality associated with a non-battery-powered card, a battery-powered card, a payment sticker, or another device (e.g., a mobile telephonic device). The GUI may be provided by a website so that a user views the GUI from a web-browser. At any time, for example, a user may change additional functionality performed at a point-of-sale purchase. A user may change the additional functionality for a card or a button of a card. A user may switch to associate a game of chance or skill to the purchase.
