BilleteScan is a free Android application designed for real-time scanning and verification of banknotes, specifically targeting Series B notes. This utility app utilizes the camera to instantly read the serial number of a bill and cross-checks it against a static table of invalid ranges. With a user-friendly fintech-inspired interface, it provides immediate visual feedback, making it a practical tool for everyday use.

The app features live scanning without the need to take photos, ensuring quick and accurate results. It highlights the initial letter of the serial number, marking it as non-prohibited if it is not 'B'. Additional functionalities include a flashlight for dark environments and an optional scan history for users wanting to keep track of previous verifications. Designed with privacy in mind, all recognition occurs locally on the device, eliminating the need for account creation or data sharing.
