Features
- Read — tag type, technology, UID, size and whether it is writable; NDEF records are shown as links, text, phone numbers, e-mail and contacts (vCard), with “Open” and “Copy”. MIFARE Classic cards show only the UID (their data is protected by keys).
- My tags — save a read tag under its own name; delete, write it to another tag or emulate it.
- Create — a new tag with a link, text, phone number or contact; save it or write it straight to a tag.
- Write — NDEF onto writable tags; the app waits for the tag and reports the result.
- Emulation — the phone answers a reader as an NFC Forum Type 4 tag while the app is open.
- 14 languages — follows the system language.

Requirements
A phone with an NFC controller available as a character device (NXP nfc_i2c, /dev/nq-nci and similar). The chip is driven by synnfcd, the synshell NFC daemon with its own NCI stack (no Linux NFC subsystem needed). Without a controller the app reports “NFC controller not found”. Saved tags: ~/.local/share/synshell/nfc/tags.json.
Install
Arch Linux (AUR) — x86_64 and aarch64. syn-nfc is part of the synshell-mobile package together with synnfcd and its systemd unit synnfc.service:
yay -S synshell-mobile-bin # prebuilt
yay -S synshell-mobile-git # built from source
Depends on synshell-core. From source: cargo build --release -p syn-nfc in the synshell repository.
Command line
syn-nfc # the app
syn-nfc --screenshot out.png --tab 1 # window snapshot: 0 — read, 1 — my tags, 2 — create
SYN_NFC_DEMO=1 syn-nfc # without the daemon: a sample read tag
Part of synshell
syn-nfc is one of the applications of synshell — a Wayland desktop environment in Rust for computers and phones, built on the syngui UI framework.
