NFC Read
Scan NFC tags, inspect NDEF records in detail, and import/export tag data via QR codes.
Overview
NFC Read lets you scan compatible NFC tags, view tag metadata and NDEF records, and keep a library of saved tags.
You can also move NDEF messages between devices using Import QR Code and Export QR Code.

Scanner Tab
The Scanner tab is the main scan screen:
- A status indicator (Ready/Scanning/Processing/Success/Error).
- Scan Tag button to start or stop scanning.
- A large NFC icon that mirrors the current scan state.
- Import QR Code button to import NDEF data from a QR code.
When a tag is read successfully (or you open a tag from Saved Tags/History), Lirum shows Tag Details so you can review what was found.
Tag Details
Tag Details is split into a few sections:
- Tag information: tag type, UID/serial number, technologies, writable state, and (when available) NDEF status and size.
- Manufacturer: when Lirum can resolve the NFC IC manufacturer from the tag's manufacturer code, it shows a friendly manufacturer name.
- Additional tag details (best-effort): extra fields depend on tag type (for example MiFare family, ISO15693 IC serial, protocol and NFC Forum data format).
- NDEF records: one or more records found on the tag.
For NDEF records, Lirum shows:
- A human-readable summary (for example a URL).
- Record metadata such as payload size, TNF (Type Name Format), record type, and identifier (when present).
- Payload data in multiple formats (for example raw hex, decimal bytes, base64, binary, and ASCII when applicable).
Tapping a record attempts a useful action when possible (for example open a URL, start a call, open Maps for a location). If a record can't be opened, Lirum copies the record content to the clipboard.
Export QR Code
From Tag Details, tap the QR code button to export the tag's NDEF message as a QR code.
This is useful for:
- Moving an NDEF message between devices without re-scanning the physical tag.
- Capturing a tag once and then using it as input for NFC Write later.
Save Tag
From Tag Details, tap Save to add the tag to your Saved Tags library.
The Save Tag sheet includes:
- A name field (used as the label in the Saved Tags list).
- Suggested names (based on the UID suffix and tag type).
- A tag preview (type, UID, and record count).
Import QR Code
Tap Import QR Code to scan a QR code that contains NFC tag data and import it into the NFC tools.
Saved Tags Tab
Saved Tags shows tags you have saved. From this library you can:
- Open tag details
- Rename or delete a saved tag (menu on each item)
- Write Now: write the saved NDEF message to another tag (when supported)
- Load: load the saved NDEF message into the NFC Write composer
History Tab
History keeps a record of recent scans (including QR imports), so you can revisit tags you've read previously.
Tap Clear History to remove all history entries on this device.
Supported NFC Manufacturers
Lirum can display a manufacturer name when it can resolve the NFC tag's manufacturer code (for example from ISO15693 tags, or from the tag identifier on some tag types). If the tag does not provide a known manufacturer code, Lirum may show an unassigned/unknown value instead.

Permissions And Requirements
- NFC is only available on supported devices and OS versions. If NFC is unavailable, Lirum shows an unavailable/permission screen.
- iOS may prompt you for NFC permission the first time you use NFC Read.
Notes And Limitations
- NFC availability depends on your device model and OS.
- Some tag types, records, and actions may be unsupported or read-only.
