Validador Meia Entrada is an Android application that verifies the authenticity of student IDs through a digital certification process. This app helps cinemas, theaters, concert halls, and other establishments to comply with the strict enforcement of Brazilian Law 12,933, which regulates half-priced tickets for students. It is a project supported by major student entities in Brazil, such as UNE, UBES, and ANPG.

The app works by scanning the QR code on the student ID and checking if the layout and digital certificate are valid, according to the standards defined by the National Institute of Information Technology (ITI). The validation process ensures that half-priced tickets are only sold to students with valid IDs, preventing the use of fake or irregular documents. The app is free to download from Google Play or App Store, and it is an essential tool for anyone who wants to verify their student ID quickly and reliably.
