About NFC Архіватар

NFC Архіватар stores files or text across multiple NFC tags and reconstructs them later. A file can be split into parts, written to tags, and restored by scanning the tags in any order. The app can optionally compress data to reduce the number of tags needed and encrypt it with AES-256-GCM using a password-derived key. The app supports several tag types, including multiple NTAG and MIFARE Ultralight variants. A compatible phone can write and read tags directly; a separately connected Chameleon device can provide additional support for MIFARE Classic cards and a block-by-block card inspector. Restored files can be opened in another app, saved to a chosen folder, or shared. NFC Архіватар works offline and uses an archive format with a header, checksum validation, and an identifier to keep the tag chunks associated. Chunks are validated and can be scanned in any order. The app is intended for users who want to keep small archives across physical NFC tags, with optional compression and password-based encryption.
