The app, called Notable Women, was developed by Google and former US Treasurer Rosie Rios. It uses augmented reality to let people see what it would look like if women were on US currency. Here’s how it works: Place any US bill in front of your phone’s camera, and the app uses digital filters — like one you’d see on Instagram or Snapchat — to overlay a new portrait on the bill. Users can choose from a database of 100 women, including the civil rights icon Rosa Parks and astronaut Sally Ride.
