What's New in Vio

2.2610.10

October 8, 2026

This release lets Vio correctly read more documents that carry only a photo, with no text fields — this now holds for every QR Code format in circulation. The notice that appears when a scan takes a while is calmer too: it waits a little longer before disappearing when you set the device down, so there is time to read it. Internal templates have been refreshed, keeping Vio current with the latest documents, and we continued strengthening the security of the integration with other apps. Update and enjoy.

Olá! Ative a opção "Leitura / Modo avançado" nas configurações do aplicativo. Nos avise se ficou mais rápida a leitura. Não esqueça de atualizar o aplicativo antes. Ok?
