3D-printed RFID Rings to Replace Fare Cards in Boston


Fare cards can be annoying, for they’re usually flimsy and easy-to-lose. A group of students from MIT have integrated high-tech solution into the system while making it fashionable to wear.

The Sesame Ring borrows design elements from the MIT class ring. These 3D-printed rings are implanted with RFID tags so all you need to do is tap them against the sensor when you’re running for the train. And because they’re 3D-printed, you can customize the color and the design down to the pattern on the ring face.

The rings can be refilled at the kiosk. They are already integrated on the entire MBTA (the Massachusetts Bay Transportation Authority) system in Boston, though the team of MIT students plans to spread the technology around the world.

The Sesame Ring is already being used by a bunch of folks affiliated with the project in Boston, and a new batch will soon arrive to hundreds of backers on Kickstarter. In the near future, the team hopes the rings won’t just be used on public transit. They’re inviting backers to vote on other uses for the rings.
