"With our wallet the entire process of identifying and sorting bills is mechanized," 16-year-old Sreya Vangara explained.
"A wallet that will be able to take a stack of bills and read them much like a printer reads paper," Stansbury added.
The students received an $8,000 grant from Lemelson-MIT to develop the wallet. The goal is to complete a prototype and present it at the EurekaFest conference in Massachusetts in June.
The team is trying to raise $10,000 to cover travel and lodging for their trip to Massachusetts. Please contact Poolesville High School if you'd like to donate.
