The 3D printed ring that acts as a subway ticket
Two young entrepreneurs from MIT Boston are currently trying to raise money on Kickstarter to finance their Sesame Ring project. Their idea is frustrated: their ticket is always lost at the bottom of their bag when it is used. To remedy this situation, they imagined a new form, easier to find and more convenient 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 just place it on the scanner to trigger the opening of the gantry. The Boston transport company is already implementing this system, but the creators intend to generalize it to public transport around the world. Another great idea that could never have been seen without the help of the 3D printer .
