NFC Tag iOS only
Little Eye reads NFC tags when you tap Scan NFC in the iOS app and hold a tag to the top of your iPhone. The NFC Tag card breaks out everything on the tag: each NDEF record — links and text codes — plus the tag's hardware ID.
Unlike the other detectors, NFC Tag is scan-triggered rather than clipboard-triggered: the card only ever appears after you start a scan yourself, so there is no Settings toggle for it. Every URL on the tag gets its own Fetch URL action, the text code is copyable, and the hardware ID (UID) is shown even for blank tags.
It cannot read bank cards or passports. Contactless payment cards don't store the NDEF records this card decodes — they speak the EMV payment protocol, which iOS does not expose to third-party apps — and e-passport chips speak the ICAO 9303 protocol, which releases nothing without keys derived from the passport's machine-readable zone. Scanning either shows at most a hardware tag ID, and most payment cards randomize that ID on every read.
NFC scanning needs a physical iPhone — the Scan NFC button doesn't appear on iPad or in the Simulator, where the NFC hardware is absent. Every iPhone that can run Little Eye has the NFC reader.
