Some MIT students (natch) say they've figured out how to build the guts of CharlieCards into stylish rings, which would let anyone, even a superhero in green tights, ride the T without fumbling for their plastic card.
They've set up a Kickstarter to raise funds for mass production of the rings via 3D printing - which they say will let them sell rings in a variety of colors and even with circuitry shaped into particular four-letter words (such as "EMMA" and "YOLO").
Having missed the train many times while fishing for our Charlie Cards (smart cards used for public transportation in Massachusetts), we looked for a solution in wearable technology. After months of hard work, we created the 3D-printed Sesame Ring, supported by the MBTA.
Now, you can walk right up to the gantry, use scientifically approved magic, and scoot on through!
The rings are actually RFID devices customized for a particular transit or ID system - the initial prototypes were built for a key system at a school in Singapore.
