The deal specifically excludes the Coin 2.0 hardware, the "universal card" that integrated every credit card you owned into one, wallet-friendly gizmo. If you own one of the units, your hardware will last for the duration of the built-in battery, which is expected to be two years. After that, however, you're SOL. In addition, Coin Rewards and the Coin Developer Program are being retired following the announcement.

Fitbit remains king of the technology hill, but its lead at the top has been eroded by Xiaomi (at the bottom end) and Apple (at the high end). In many ways, buying Coin is a defensive move against the latter, since its rival wearable already offers mobile payments technology.
