Editorial interest 82/100 Selection signal · not a rating of the site

A cross-platform desktop tool for authorized NFC card inspection, reading, writing, dumping, key management, and access recovery.

Landing page captured for the 2026-09-14 issue.

Field notes

The workflow starts with reader discovery and card inspection, then moves through authenticated block reads and edits, raw-dump handling, key scanning, and a PN532 UART recovery path. NFCX says it verifies writes by reading them back and guards operations involving dump geometry, BCC, access bits, card changes, and block 0. Its release profile is tested with PN532 UART plus FT232RL across macOS, Windows, and Linux; other adapters require drivers and serial permissions.
