NFC Write

Compose and write NFC messages, or perform advanced tag operations (device dependent).

NFC Write: Compose and Advanced.

Compose: build a message by adding records, or load from Saved Tags.

Compose: scroll to see the Write button and additional options.

Overview

NFC Write lets you create an NDEF message (a set of records) and write it to a compatible NFC tag. It also includes an Advanced tab for operations like copy, erase, lock, and format.

Compose Tab

Compose is where you build what you want to write:

• Saved Tags: open your saved tag library and choose Write now or Load to composer.
• Import QR: import NFC data from a QR code.
• Export QR: export the current message as a QR code (when a message exists).
• Add Record: add one or more records to the message.

Depending on your state, Compose can show:

• An empty state (no records added yet)
• A record list (when records exist)
• An imported message view (when imported QR data provides a full message override)

Import And Export QR

Use QR import/export to move NFC messages between devices or share a composed message.

Writing A Tag

When you tap Write, iOS opens the system NFC writing session. Keep the NFC tag close to the top of the device until the operation completes.

If an error occurs, Lirum shows a detailed error sheet.

Advanced Tab

Advanced includes operations such as:

• Copy Tag
• Erase Tag
• Lock Tag
• Format Tag
• Copy To Infinity (repeat/multi-write workflow)

These operations run through the system NFC session and may not be supported by every tag type.

Safety Notes

• Lock and format/erase operations can be permanent. Only use them if you understand what your tag supports.
• Start with a spare tag when experimenting.

Notes And Limitations

• NFC availability depends on device model and OS.
• Some tags are read-only or do not support writing/locking/formatting.
