Ultra-Thin 4×4mm NFC RFID Sticker Tags – NTAG213 Programmable Micro Labels

Meet the world's smallest workhorses of wireless data transfer. These ultra-compact 4×4mm NTAG213 NFC RFID sticker tags pack powerful near-field communication technology into a near-invisible label — perfect for access control systems, supply chain tracking, asset management, smart packaging, and countless DIY automation projects. Each pack includes 10 NFC tags, ready to program straight out of the box.

Key Features

Micro Form Factor: At just 4×4mm — roughly the size of a fingernail — these stickers fit discreetly on almost any surface without adding bulk or drawing attention.
NTAG213 Chip: Industry-standard NTAG213 IC with 144 bytes of user memory, fully compatible with NFC-enabled smartphones, tablets, and readers that support ISO 14443A.
Fully Programmable: Write URLs, text, vCard data, app links, custom commands, or any NDEF-formatted payload using any free NFC writing app (e.g., NFC Tools on iOS or Android). No additional hardware required.
FPC Flexible Construction: Built on a Flexible Printed Circuit (FPC) substrate, these tags bend slightly to conform to curved or uneven surfaces without compromising performance.
Moderate Read Range: Optimised ~1mm read distance pairs perfectly with the miniature size — ideal where precision, concealment, and security matter most.
Versatile Applications: Access control, inventory & supply chain management, smart product authentication, event ticketing, retail labels, and maker/IoT projects.
Self-Adhesive Backing: Peel-and-stick design allows fast, clean attachment to paper, plastic, metal-free surfaces, packaging, and more.

Frequently Asked Questions

Q: What devices are compatible with these NTAG213 NFC sticker tags?

A: These NTAG213 NFC RFID sticker tags are compatible with any NFC-enabled device that supports the ISO 14443A standard and NDEF data format. This includes most modern Android smartphones, iPhones (XS and later), NFC card readers, and access control systems operating at 13.56 MHz.

Q: How do I program these NFC sticker tags?

A: Programming is simple and requires no specialist hardware. Download a free NFC writing app such as "NFC Tools" on iOS or Android, hold your NFC-enabled phone near the tag, and write your desired data — URLs, text strings, vCard contacts, app deep links, or custom NDEF records. The process typically takes just a few seconds.

Q: Can these NFC tags be rewritten or are they one-time use?

A: NTAG213 tags are rewritable by default. You can overwrite the stored data as many times as needed. They can also be permanently locked (write-protected) once your final data is programmed, preventing further modification — ideal for product authentication or secure access control applications.

Q: Why is the read distance only ~1mm on such a small tag?

A: The read distance is directly related to the antenna size. At 4×4mm, the antenna is extremely small, which limits the inductive coupling range to approximately 1mm. This is intentional for applications where precision placement, discretion, and tap-to-read security are required — ensuring only deliberate, close-proximity scans succeed.
