Features & Capabilities

DUApp is a streamlined Chrome extension designed to read the data embedded in the UniQode® barcode of the Certificate of Registration, known as the Unique Automotive Document in Portugal. This app provides users with quick and easy in-app access to complete document details in an intuitive user interface. It's a helpful tool for anyone needing to verify or review vehicle registration information digitally. However, DUApp is not intended to replace the physical Certificate of Registration document itself.

User Reviews

The DUApp has mixed reviews with several users unable to scan their cards successfully despite adequate lighting and multiple tries, indicating unreliable code reading functionality. Some devices experience better performance but overall the app struggles with reading QR codes or UniQode, lacks data saving capabilities, and does not support scanning codes from gallery images. While paper QR codes can sometimes be read, perspective distortion causes issues. Users express frustration with error messages and limited features, though a few find it works as expected on certain phone models.

Pros

Works well on certain devices (e.g., Samsung Note 20, OnePlus 6)
QR code reading for paper documents functions correctly
App has potential usefulness when it successfully reads codes
Some users found reading QR codes possible with proper main camera usage

Cons

App frequently fails to read QR codes or UniQode on cards despite good lighting and multiple attempts
Does not save or store read data, limiting its usefulness
Lack of support for reading QR codes from gallery images
Frequent error messages instructing users to try later without resolution
Poor handling of perspective or skewed images leading to failed scans
