"NFCWriter" is an extremely lightweight Android app designed for writing files on a byte level to NFC tags. Unlike most apps on the Play Store, it allows users to select a mime type and write corresponding files directly to NFC tags. Additionally, users can opt for ZLIB compression, enhancing compatibility with apps that support this format, including NFCShell, NFCWebView, TagSH, and Illud. This app is ideal for developers and tech enthusiasts looking to utilize NFC tags for advanced file handling.
