Valida tu billete Serie B is a free Android application designed for users in Bolivia to quickly and securely check the validity of their Bolivian bills from the 'Serie B' (Bs 10, Bs 20, and Bs 50). Following a temporary invalidation of certain bill serial numbers by the Central Bank of Bolivia (BCB) after an incident, this tool helps users avoid accepting or distributing invalid currency in everyday transactions. The app features a smart camera scanner for real-time scanning of bill serial numbers and allows for manual entry of digits as an alternative.

Key features include offline functionality, ensuring accessibility without an internet connection, and an integrated database for seamless operation. Users can also access official guidelines and the list of invalidated serial numbers, promoting informed transactions. With a focus on privacy, the application does not require registration, ensuring all operations are conducted locally on the user’s device.
