In Boston, you can now wear your bus or subway pass- as a piece of jewelry. The Massachusetts Bay Transportation Authority (MBTA) has recently started selling rings of 3D printed wearable technology that have a chip in them that acts as their bus pass. So not only do the people who own them look like they have some pretty unique jewelry, they also look pretty cool when they ‘fist bump’ to pay for their ride on public transit.
Another cool thing about this jewelry? It came about because of a Kickstarter campaign. Boston Magazine has more details.
