Validar Billete Serie B is a utility app designed for the Bolivian population, enabling users to quickly verify the status of their currency. The application checks if a specific serial number belongs to a bill that has been invalidated by the Central Bank of Bolivia (BCB). It offers a straightforward user experience with features such as text recognition through the camera, ensuring fast and efficient validation. In dim lighting conditions or if the bill is damaged, users can also input the serial number manually via the keyboard.

This app operates autonomously without requiring internet connectivity, making it a reliable tool for daily use. Importantly, it prioritizes user privacy by not collecting or transmitting any data, images, or personal information externally. All validation processes occur locally on the device, utilizing publicly available parameters from official BCB communications for accuracy in bill verification.
