Quét Căn Cước Công Dân is an Android application designed to facilitate the reading and management of information from Vietnamese citizen ID cards. This free utility allows users to scan QR codes directly from the ID card or from stored snapshots, providing a convenient way to access personal information quickly. Users can also look up old ID card numbers and read data stored in the CCCD chip, with the option to display and save a PDF version of the ID card image.

The application features capabilities for copying information from the CCCD card and allows users to review their scanning history. Data can be exported in CSV format for reporting purposes, and all scanned data is securely encrypted to ensure privacy. With a lightweight design and user-friendly interface, Quét Căn Cước Công Dân is accessible for all users and functions entirely offline, ensuring that no personal information is collected during its use.
