The RumbaTime's Perry GO

Leave your cash at home next time you go for a run/go to the gym/go for a run… to the gym (!) and instead opt for RT's just-dropped, preppy wrist-ticker that sports an interchangeable striped nylon strap with a built-in contactless NFC payment card you can load up online and swipe at checkout in any store with a key fob payment thingy.
