Bay Area resident Amy Wibowo was always losing her BART Clipper card so she got creative! She made her
She said: “I figured if I had my BART card on my ring then I would just know where it is and I could just tap my hand."
To make the ring, she soaked the clipper card in acetone for four days so it would dissolve, exposing the RFID chip.
Then she experimented with how to transfer the delicate parts into resine.
Wibowo then added in a few flower petals to make it pretty.
The 33-year-old says she has no plans to market this idea.
It's her way of making something useful, and beautiful.
