Our RFID FPC MINI tag delivers enterprise-grade performance in an ultra-compact form factor. Starting at just 3×3mm—the smallest available—these flexible tracking tags feature advanced FPC substrate technology with less than 0.5% defect rate. With production capacity exceeding 500 million units annually and rapid prototyping within 7 working days, WS-RFID Technology combines 15+ years of expertise with automated manufacturing across our 10,000㎡ facility. Choose HF 13.56MHz or UHF 860-960MHz frequencies, both compliant with ISO/IEC 14443 and EPC Gen2 protocols for seamless integration.
You need tracking solutions that fit where others can't. Our miniature tags bend, flex, and perform in the tightest spaces.
Size That Breaks Boundaries
We've engineered the smallest product in the market. At 3×3mm, it fits inside TWS earbuds, jewelry pieces, and medical devices. You won't sacrifice functionality for size.
Flexible By Design
The FPC substrate bends around curved surfaces. Install it on smartwatches, jewelry, or irregular shapes. Your installation challenges become simple solutions.
Dual Frequency Options

: QHow small can these tags actually get?
Our smallest production unit measures 3×3mm. We can customize even irregular micro-shapes based on your specific space constraints.
Q: Can they survive harsh environments?
Yes. These tags operate reliably from -25°C to +70°C. The flexible FPC construction resists bending stress and adapts to curved mounting surfaces.
Q: What's the read range I can expect?
HF versions read from 0-3cm, perfect for precise identification. UHF options extend to 0-10cm for faster bulk scanning applications.
Q: Do you support small quantity orders?
Absolutely. We handle everything from sample testing batches to 500+ million unit annual volumes. Small-batch customization is available with competitive lead times.
Q: How do I integrate these into my products?
Choose between soldering for permanent installation or adhesive bonding for simpler applications. Our engineering team provides mounting solutions tailored to your assembly process.
Q: What chip options are available?
We offer NXP NTAG series for HF applications and Impinj Monza series for UHF needs. Both deliver reliable performance compatible with mainstream reader infrastructure.
Q: Can you customize the shape?
Yes. Our advanced antenna design capabilities support irregular shapes and custom dimensions. Share your requirements, and we'll engineer a solution that fits.
