Engineered for Maximum RF Efficiency & Redundancy
Unlike mass-produced commodity tags, the Vanmen AeroTag 13.56 was conceived and designed from the ground up in KiCad to solve read-field nulls, optimize Q-factor, and bridge wireless NFC with embedded systems.
Concentric Dual-Channel
The 13.56 MHz planar spiral coil encircles the central laser-etched QR code. If the user's device has NFC disabled, the camera instantly scans the fallback QR code without any dead zones.
RF Energy Harvesting
The NXP NT3H2111 silicon scavenges electromagnetic field energy during an active tap, outputting up to ~2.9V DC onto the VOUT pad to illuminate indicator LEDs or power ultra-low-power sensors.
Tuned 7 pF C-Match
A calibrated high-Q C0G/NP0 dielectric ceramic capacitor matches antenna inductance to achieve a sharp S11 notch (< -22 dB) at exactly 13.56 MHz, yielding superior 25 – 45 mm read distances.
I2C Embedded Bridge
Exposed solder pads connect directly to STM32, ESP32, or RP2040 microcontrollers over I2C. Transfer configuration parameters or firmware diagnostics between phones and embedded hardware seamlessly.

Engineering & Order FAQ
How do I program or update the data on the NFC tag?
The Vanmen AeroTag 13.56 conforms to NFC Forum Type 2 Tag specifications and can be read or written instantaneously using any standard NFC smartphone app (such as NFC Tools, available free on iOS and Android) or via Web NFC in compatible browsers. You can write websites, contact vCards, Wi-Fi credentials, text, or automation triggers. You can rewrite it up to 200,000 times, or permanently lock blocks if desired.
Does the recipient need a dedicated app to read the tag?
No app is required! Modern iPhones (iPhone XS and newer) and all NFC-enabled Android devices feature native background NFC tag reading. When the phone is brought within 25–45 mm of the tag, a native OS notification banner automatically pops up prompting the user to tap and open your link or contact card.
How durable is the PCB tag compared to standard plastic stickers?
Traditional paper or plastic NFC stickers peel off, crack when bent, and attenuate near metal. The Vanmen AeroTag is fabricated from high-grade TG150 FR-4 fiberglass composite with 1 oz copper and Electroless Nickel Immersion Gold (ENIG) or Lead-Free HASL finish. It is scratch-resistant, water-resistant, rated for -40°C to +85°C operation, and retains memory for over 20 years.
Can you manufacture custom shapes, silkscreen artwork, or large enterprise volumes?
Yes! We handle full in-house KiCad RF antenna layout, bespoke planar geometries (keychain tags, credit card form factors, machine badge mounts), serialization, custom silkscreen logos, and automated SMT assembly. For production orders of 25 to 10,000+ units, reach out to our engineering lab for direct volume pricing.
How does the RF Energy Harvesting feature work?
The onboard NXP NT3H2111 IC scavenges high-frequency electromagnetic energy from the smartphone's 13.56 MHz transmitter field. It outputs up to ~2.9V DC (up to 5 mA) on its VOUT pin, allowing you to illuminate an indicator LED, power low-energy digital sensors, or wake up a connected ultra-low-power microcontroller without any battery.
Can I integrate this tag with a microcontroller like STM32 or ESP32?
Yes! Unlike simple RFID stickers, the NXP NT3H2111 provides a dual-interface architecture: contactless RF (13.56 MHz) plus a high-speed wired I2C bus with a configurable Field Detect (FD) interrupt pin. We expose the I2C pads (VCC, GND, SDA, SCL, FD) on the back of the PCB so you can solder header pins or wires directly to your embedded board.
Need Custom Antenna Geometry or Volume SMT Manufacturing?
We design bespoke multi-layer planar coils, custom form factors, metal-immune ferrite backings, and embedded IoT integrations for clients worldwide.
