Validador Meia Entrada is the official application for reading the QR code of the student ID and verifying the layout and digital certificate's validity. The app ensures compliance with the Brazilian law of half-priced tickets for students, allowing real-time consultation of the student's status.

The app verifies the authenticity of the student ID to prevent the purchase of half-priced tickets with fake or irregular student IDs. It assists cinemas, event producers, theaters, concert halls, and other establishments in strictly complying with the Half-Price Law. The app also prevents students from buying fake documents that do not comply with the national standard or the law.

The validation process checks if the certificate digital and requirements are in accordance with the premises defined by the National Institute of Information Technology (ITI).
