SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill simplifies programming a single NFC tag by guiding payload entry, tag detection, write, read-back verification, and audit logging.

Core Features & Use Cases

Write a payload to an NFC tag (URL, text, or raw NDEF) and verify the result.
Supports optional tag labeling for audit trails and end-to-end single-tag workflows.
Use cases include configuring access tags, device pairings, and quick tag updates in controlled environments.

Quick Start

Provide the payload value and type, then present the tag to the reader to perform the write and verification.

FAQPage Schema

How do I write a URL or text payload to an NFC tag and verify it?▼

To write a URL or text payload to an NFC tag, provide the payload value and type, present the tag to the reader, and the system will write the NDEF data and verify the result by reading it back.

What tools do I need to program an NFC tag using NDEF payloads?▼

Programming an NFC tag requires access to NFC reader tools like nfc-list, nfc-mfclassic, and nfc-mfultralight to detect the hardware and write the NDEF payload successfully.

Can I add a label to an NFC tag for audit logging purposes?▼

Yes, you can assign an optional label during the NFC tag writing process to maintain audit trails, with logging output directed to a specified CLAUDE_USER_DATA path.

How does the NFC tag writer handle locked tags?▼

The NFC tag writing process includes safe handling for locked tags, ensuring the workflow manages read-only hardware gracefully without causing failures during the write verification step.

What is the best way to program a single NTAG for device pairing?▼

For single-tag programming workflows like device pairing, provide the raw NDEF payload to the system, present the NTAG to the reader, and it will handle the write and read-back verification.
