MIT students develop 3D-printed ‘Sesame Ring’ to replace public transit cards | 3ders
It is very convenient to take public transportation in big cities, but sometimes it is annoying and time consuming fishing through your purse for your transit card.
Two undergraduate students at MIT has created the 3D-printed “Sesame Ring” to replace Boston’s transit card, the Charlie Card, after they became frustrated at constantly losing their passes at the bottom of their bags.
Nice, silly, loose, and unrealistic thinking.
