NFSee - NFC Card Helper2.4.0

Bring a transit, bank, or identification card—or another NFC tag—near a compatible phone to have NFSee read and dump the data it exposes. It supports various types of NFC tags and cards, giving users a way to inspect information stored on contactless media directly from a mobile device. The app is useful for developers examining NFC data during testing, as well as people checking what supported cards and tags return.

Built with Flutter, NFSee runs on Android and iOS while keeping its core reading purpose consistent across both platforms. On an Android phone, it can work with the NFC capabilities used by transit cards, bank cards, identification cards, and standalone tags. Its placement in Developer Tools reflects this practical focus on accessing and examining card and tag data rather than managing payments or travel accounts.

The Android version requires Android 8.0 or newer and the arm64-v8a architecture. The current release is version 2.4.0, and the project is open-source. NFSee does not replace a card’s service or account system; it reads the NFC data made available by the card or tag and presents that information for inspection.
