What causes NFC cards to brick during writes?

Tear-off effect: RF field drops mid-write, partial data corrupts sectors, apps detect inconsistency and lock out.

How does LCOW prevent NFC bricking?

Never overwrites data—instead appends shadows, flips atomic anchor pointer last; interruptions leave old version intact.

Is AECardTools open source for NFC storage?

Project shares core engine concepts; check GitHub for Python/Kotlin code to adapt your apps.
