The Cash Assist mobile app, available now on Google Play store for Android and Apple App Store for iOS, is the perfect training companion for cash handlers across industries who need guidance on how to authenticate Federal Reserve notes.

The app’s “Denomination Detector” uses your Apple or Android’s camera to identify the denomination of the bill you are authenticating. Capture an image of your banknote with either the front-facing or back-facing camera on your mobile device. Once the denomination has been detected, the app will display the key security features that are visible on genuine currency.

The app’s “Tilt Check Simulator” reveals how the security features of banknotes function when in motion.  Select a denomination and tilt your phone back and forth to interact with a virtual banknote and observe its unique features from different angles.  If your goal is to quickly access text about the security feature of specific banknotes, use the app’s “Quick Pick” feature. This will present information about key security features for each denomination within the app and direct you to the Denominations page on uscurrency.gov for additional details.

From small business owners to store employees, anyone can use the app to stay updated on the latest security features of U.S. currency. Please note that Cash Assist does not identify counterfeits for you.
