TECH INNOVATOR: Elizabeth Nyamwange designed Etana to help women in developing nations.

In the U.S., people can use their birth certificate, driver’s license, or passport to prove who they are. But about 1 billion people worldwide lack official proof of identity. Many are women in low-income countries. Without legal identity, everyday tasks like opening a bank account or buying a cell phone can become impossible.

Sixteen-year-old Elizabeth Nyamwange, who’s originally from Kenya and now lives in Illinois, wanted to find a solution to this problem. She invented Etana, a solar-powered fingerprint scanner. The device creates a digital proof of identity—without requiring access to internet or electricity.

IDENTIFICATION DEVICE: Elizabeth Nyamwange has invented Etana, a solar-powered device that scans fingerprints to create digital proof of identity.

The scanner converts each fingerprint into binary code—a unique series of 1’s and 0’s—and uploads it to a secure server. “Etana generates fully anonymous signatures which cannot be hacked, faked, cloned, or stolen,” says Elizabeth. Next, Elizabeth is excited to do a small pilot, or test of her invention, with women from her hometown in Kenya.
