It is not intended for detecting counterfeit notes or notes used for games.

To use the app, the user simply needs to launch it and point the smartphone's camera at the banknote. By touching the screen, the app starts recognition and displays the result in the aforementioned forms. The app is also compatible with TalkBack and Braille displays, ensuring accessibility for the blind and deaf-blind community.

Overall, Определитель купюр is an innovative and user-friendly app that provides significant assistance to visually impaired individuals in their daily lives.
