The US Patent and Trademark Office on Tuesday published 58 newly granted Apple patents, but one that envisions communication between a device like the iPhone or iPad and a wireless disposable wristband has received some attention.

The patent, which was earlier reported on by Patently Apple, covers technology for an “autonomous battery-free microwave frequency communication device” that could be embedded on physical objects such as a wristband, flyer, or card.
