System Documentation

What problem does it solve?

Deep inspection of an NFC tag's hardware properties, memory layout, lock state, and capacity. Useful for diagnosing why writes fail or whether a tag is locked/read-only.

Core Features & Use Cases

  • Identify tag type and UID using nfc-list to verify compatibility with write or password-protection flows.
  • Assess memory layout and capacity for NTAG21x and MIFARE Classic to plan safe data writes.
  • Analyze LOCK bits, CC bytes, AUTH0 (where present) and sector/trailer access bits to guide password protection decisions.
  • Non-destructive read-only reporting to troubleshoot issues without modifying the tag.
  • Use-case guidance for pre-write diagnostics and validation before write operations.

Quick Start

Present a tag to the reader and run the inspection to produce a diagnostic report of its hardware properties and memory layout.
