NFC Epoxy Tag

Union Smart manufactures premium, highly durable NFC Epoxy Tags and RFID Key Fobs for global B2B enterprises, system integrators, and pet accessory brands. Combining the power of NFC wireless communication with a tough, IP67 waterproof epoxy resin coating, these domed tags are built to survive environments where standard paper or PVC stickers fail. Benefit from our factory-direct wholesale pricing, OEM custom printing, and bulk chip encoding with an MOQ starting at 1,000 pcs.

Custom NFC Epoxy Tags & Waterproof RFID Key Fobs

Unlike standard NFC stickers, our resin domed NFC tags feature a thick, crystal-clear layer of hardened epoxy. This specialized coating not only gives the tag a premium, 3D glossy appearance but also completely seals the internal RFID antenna and silicon chip. The result is a rugged, weatherproof smart tag that can withstand heavy impacts, continuous moisture, and daily outdoor wear and tear.

With a simple tap from any NFC-enabled smartphone (iOS or Android), users can instantly trigger URLs, digital business cards, product authentication protocols, or access control systems—no app required.

Key Manufacturing Features

• IP67 Waterproof & Weatherproof: The epoxy resin dome completely waterproofs the tag, protecting it from rain, dust, UV rays, and harsh outdoor climates.
• Anti-Metal NFC Options Available: Standard NFC tags fail on metal surfaces. We can integrate a specialized ferrite isolation layer, creating anti-metal NFC tags that work perfectly when mounted on industrial machinery, scaffolding, or metal laptops.
• Impact-Resistant Design: The hard epoxy shell prevents the internal antenna from bending or breaking, making it ideal for high-friction uses like keychain fobs and pet collars.
• Universal Smartphone Compatibility: Embedded with genuine NXP NTAG series chips, ensuring instant tap-to-read functionality on all modern smartphones.

Premium Chip Selection

We supply and encode custom epoxy tags utilizing the exact silicon required for your project:

• NXP NTAG213 (144 Bytes): The industry standard for URLs, social media links, and smart pet ID tags.
• NXP NTAG215 (504 Bytes): Larger memory ideal for vCard digital business cards and Amiibo cloning.
• NXP MIFARE Classic 1K / DESFire EV3: High-security chips specifically designed for RFID access control key fobs, hotel access, and gym memberships.

Top B2B Industry Applications

• Smart Pet ID Tags: Extremely popular for modern pet tracking. Attach a custom-branded NFC epoxy tag to a dog or cat collar. If the pet is lost, anyone who taps the tag with their phone instantly sees the owner's contact info, vet records, and return instructions.
• Access Control Key Fobs: Replace standard boring access cards with fully branded, waterproof RFID keychains for corporate offices, apartment complexes, gyms, and hospitality venues.
• Smart Vehicle & Device Keys: Used as physical NFC keys for unlocking smart electric scooters, starting smart home devices, or verifying shared rental equipment.
• Industrial Asset Tracking: Combined with our anti-metal layer, these tags can be permanently adhered to metal tools, IT assets, or outdoor scaffolding for rapid inventory scanning.

OEM Customization & Manufacturing Specifications

As a direct B2B factory, Union Smart provides full personalization to match your corporate branding:

• Custom Shapes & Sizes: Standard round (25mm, 30mm) or square (30x30mm) tags. Custom die-cut shapes (hearts, bones, shields) are available upon request.
• Full-Color Printing: CMYK high-resolution offset printing beneath the epoxy dome for vibrant, non-fading logos and artwork.
• Variable Data Printing (VDP): Laser-engraved UID numbers, sequential serials, and QR codes printed directly on the PVC base.
• Bulk Chip Encoding: High-speed automated encoding of your URLs, vCards, or proprietary access control data.

Frequently Asked Questions (FAQ)

Q1. What is the difference between a standard NFC sticker and an NFC Epoxy Tag?

Standard NFC stickers are made of paper or thin PET and can be easily scratched, torn, or ruined by water. An NFC Epoxy Tag covers the printed surface and chip with a thick, hardened resin dome. This makes the tag rigid, 100% waterproof, and incredibly durable for outdoor or keychain use.

Q2. Do I need an anti-metal NFC tag?

If you plan to stick the epoxy tag onto any metal surface (like an aluminum laptop, metal scaffolding, or steel machinery), standard NFC tags will short-circuit and fail to read. You must request our anti-metal layer, which adds a shielding ferrite material to the back of the tag to ensure perfect functionality on metal.

Q3. Which chip should I choose for NFC Pet ID Tags?

The NXP NTAG213 is the global standard for smart pet ID tags. It has enough memory to store a unique URL linking to the pet's cloud profile, and it is universally readable by any iPhone or Android device without an app.

Q4. Can you make these tags as RFID key fobs with a hole for a keyring?

Yes. Many of our clients order NFC epoxy tags with a pre-punched hole and an elastic string or metal split-ring attached. These are heavily used as branded access control fobs for gyms, apartments, and corporate offices.

Q5. Do you offer wholesale pricing for bulk B2B orders?

Absolutely. As an OEM manufacturer, our pricing is designed for scale. Our standard MOQ is 1,000 pieces, but we offer highly aggressive tiered pricing for major pet accessory brands, access control integrators, and marketing agencies ordering in the tens of thousands.
