This device uses an ESP32 to access the internet via a hotspot on your phone. It accesses the current exchange rates of USD to preset currencies of another country. Then it displays this information on the screen in the center of the device. This device would assist those who are American, but live or are traveling in a different country. It is safer to use in public than a smart phone, and it provides a way to spend less time on your phone. This device would be most useful in a market or grocery store, so that the user would know exactly how much money they were spending.
