The ring printed in 3D that acts as a metro ticket
Two young entrepreneurs from MIT Boston are currently trying to raise funds from Kickstarter to finance their Sesame Ring project. Their idea is frustrating: their ticket is always lost at the bottom of their bag when they use it. To remedy this situation, they devised a new shape, easier to find and more practical to use: a ring printed in 3D. This object is printed in 3D, which makes it fully customizable. The ring is printed around an electronic chip, so simply place it on the scanner to trigger the opening of the gantry. The Boston transit company is already implementing this system, but the creators intend to extend it to public transit around the world. Another excellent idea that would not have been possible without the help of the 3D printer.
