What is a crash-proof NFC storage engine?

It's LCOW: append-only writes, atomic anchors. Bricking impossible on MIFARE 1K—even mid-RF drop.

How does AECardTools reclaim 900 bytes from 1KB?

Dumps sector keys to app DB. Treats trailers as data canvas. Encrypted, secure.

Will this work on my Android phone?

Yes—NFC-enabled. Kotlin app. Python under hood. Open source, free.
