PassportImageDecoder is an open-source library used for decoding various image formats used in electronic machine-readable travel documents (eMRTD)/electronic passports (ePassport). This library is developed by NFC Research Lab and is licensed for free. It is compatible with Android 9.0 and is used by NFC TagInfo to decode images from ePassports.

The library provides a reliable solution for decoding images from ePassports, ensuring that the data is accurate and can be easily read by any application. It is a valuable tool for developers who need to work with ePassports and eMRTDs. However, it is important to note that while the library is tested prior to release, there may still be errors that cause unexpected behavior or functional interruptions. In such cases, users are encouraged to provide crash reports to help improve the library.
