Token Smart Watch
If this is as awesome as it looks then we're all in luck because it's beautiful. The smart ring has multiple functions that seem to focus on using the ring to replace all your scannable. From Apple ID to a variety of RFID supported technologies.
It would be great if we knew for sure wether or not it would be compatible with all scannables, like gym fobs, and different public transit passes. Head over to their website to watch their awesome promo video and to learn more about them.
