Programmable Mini NFC Tag NTAG213 – 7x7mm Anti-Metal FPC

Programmable 7x7mm Micro FPC NFC Tag – NTAG213 Anti-Metal

Meet the smallest smart tag in your toolkit. This ultra-compact 7x7mm programmable NFC tag features flexible FPC (Flexible Printed Circuit) construction with anti-metal properties, making it ideal for mounting on metal surfaces where standard NFC tags fail. Powered by the reliable NTAG213 chip and operating at the universal 13.56 MHz frequency, it enables fast, contactless data transfer — no batteries, no cables, no fuss.

Whether you're automating your smart home, tagging equipment, pairing Bluetooth devices, or building creative DIY electronics projects, this micro NFC tag delivers consistent, dependable performance in a form factor small enough to go virtually anywhere.

Frequently Asked Questions

Q: What devices are compatible with this NTAG213 NFC tag?

A: This NFC tag is compatible with any NFC-enabled device that supports the ISO 14443A standard, including most modern Android smartphones, iPhones (iPhone 7 and later with iOS 14+), NFC card readers, and various smart home automation hubs. No special app is required for basic tap-to-read functionality.

Q: Why is this NFC tag described as "anti-metal" and why does that matter?

A: Standard NFC tags perform poorly when placed directly on metal surfaces because metal disrupts the electromagnetic field needed for communication. This tag's flexible FPC (Flexible Printed Circuit) construction includes a ferrite-based layer that isolates the antenna from metallic surfaces, enabling reliable read/write performance even when the tag is mounted on metal equipment, enclosures, or tools.

Q: How do I program this NFC tag?

A: You can program this NTAG213 tag using any free NFC writing app (such as NFC Tools, available on Android and iOS) and an NFC-enabled smartphone. Simply open the app, select "Write," choose your data type (URL, text, contact, automation action, etc.), and tap your phone to the tag. The tag can be rewritten up to 100,000 times, and you can also lock it to make it read-only.

Q: What is the sensing (read) distance of this tag?

A: The typical sensing distance is approximately 10–20 mm, though the actual range depends on the NFC reader being used. High-sensitivity readers may achieve slightly greater distances, while lower-powered readers may require closer contact.
