About this app

NFC Reader is a diagnostic tool that utilizes the NFC functionality of Android phones to quickly verify basic information disclosed by NFC cards and tags.

Key Features

- Scan NFC cards/tags

- Check UID, ATQA, SAK, and Technology Type

- Display memory, sector, and block structures in MIFARE Classic

- Detect NDEF and check writability

- Diagnose card/protocol compatibility based on Android

- Save scanned card information internally on the device

- Name saved cards and check recent scan history

- Remove ads and unlock card storage limits in Pro

- Export JSON/TXT diagnostic reports per card in Pro

Compatibility diagnostics use only information that Android can publicly verify from the card. Since the authentication methods of actual external readers or controllers cannot be verified simply by scanning the card, the app distinguishes between verifiable and non-verifiable ranges.

Privacy

Scanned NFC card information is stored internally on the user's device and is not transmitted to a separate server by the app operator. The Google Mobile Ads SDK may be used to provide ads in the free version, and a privacy selection screen is provided in regions where necessary.

This app is a tool for analyzing NFC cards and verifying compatibility. It does not provide functions to extract or modify security credentials or bypass access controls.
