NFC Tag Manufacturer in China

Every NFC tag we ship is built on our own Shenzhen line

'Made in China' hides a wide range — from a factory that bonds its own chips to a trading desk that photographs someone else's. Proud Tek is the first kind: we etch or print the antenna, flip-chip bond the NXP silicon, convert the inlay, print your artwork and encode the data, then read-verify each unit before it leaves our Shenzhen factory. Start with a free NFC sample pack, or jump to the parts most buyers order — NTAG 213 NFC stickers. The numbers below are the ones a procurement team checks first.

• 2008Manufacturing NFC since
• 10Automated lines, 2 factories
• 305+Production & test machines
• 50+Export countries

• Full form-factor range from one line — paper and PET stickers, wet and dry inlays on rolls, epoxy hard tags, anti-metal tags and tamper-evident labels — so a mixed NFC program ships against one purchase order, not five.
• Own-the-line process — antenna etching and printing, flip-chip bonding, reel-to-reel converting, offset and screen printing and inline encoding all happen in-house, so lead time and quality are ours to control, not a subcontractor's.
• NXP-allocated silicon — we run NTAG 213/215/216, NTAG 424 DNA, MIFARE Ultralight and ICODE SLIX2 from NXP and NXP-authorised distribution, with STMicroelectronics ST25TA and Fudan compatibles offered only where a program is explicitly cost-driven.
• Converter- and integrator-ready output — inlays delivered on rolls in standard pitches for label converters, tags supplied bare for lamination, and print-and-encode stickers finished to your artwork from a 25 mm round inlay up.
• Compliance manufactured in, not bolted on — RoHS, REACH SVHC, CE and FCC material and radio declarations per shipment, with quality records retained seven years under ISO 9001.

The NFC chips and form factors we manufacture

This table is the fast way to see whether we already build your part. Everything here runs at 13.56 MHz to a published air-interface standard — ISO/IEC 14443 for NTAG and NTAG 424 DNA, ISO/IEC 15693 for ICODE — so a tag encoded on our line today keeps reading across a phone or reader fleet's lifetime. Minimums below are our standard manufacturing MOQs; browse live parts on the NFC labels catalogue and NFC wet inlays.

• NTAG 213 — 144 bytes user memory, NFC Forum Type 2 tag, ideal for URL encoding, product authentication and marketing stickers where cost efficiency matters.
• NTAG 215 — 504 bytes user memory, commonly used for gaming NFC (Amiibo compatible), loyalty programs and applications needing more data storage.
• NTAG 216 — 888 bytes user memory, the largest NTAG chip for vCard storage, complex NDEF records and multi-record applications.
• NTAG 424 DNA — AES-128 mutual authentication with a SUN (Secure Unique NFC) message that generates a fresh cryptographic code on every tap, for anti-counterfeit and cloud-verified product authentication (NFC Forum Type 4).
• MIFARE Ultralight EV1 — up to 128 bytes user memory with an originality signature and one-time-programmable counters, for single-use tickets, transit fares and event access.
• ICODE SLIX2 — an ISO/IEC 15693 vicinity chip at 13.56 MHz built for longer HF read range in library media and industrial-automation tagging.

Inside the line: how an NFC tag is manufactured

A datasheet makes an NFC tag look like one part; the factory floor knows it is five. Here is how a bare NXP wafer becomes an encoded, read-tested tag on our line — antenna first, silicon second, and the QC read-test that decides whether a unit ships at all. Nothing in this sequence is subcontracted to a job shop, which is why a program that mixes form factors can still ship on one production traveler.

1. 1. Antenna

   The aluminium or copper antenna is etched or printed onto a PET or paper web and matched to the target chip and surface — the geometry that decides read range is set here, not bought off a shelf.

2. 2. Chip bonding

   NXP wafers are flip-chip bonded to the antenna to form the inlay, with an originality-signature check so the silicon on the line is the silicon on the quote.

3. 3. Converting

   Inlays are laminated wet or dry and die-cut to size, delivered on continuous rolls in standard pitches for label converters or singulated for hard-tag assembly.

4. 4. Printing & finishing

   Full-colour artwork is offset-, screen- or digitally printed and laminated; epoxy and anti-metal tags are domed or molded into their housings.

5. 5. Encoding & QC

   NDEF records or NTAG 424 DNA SUN messages are written inline, every unit is 100% read-tested, and a batch report with chip response and read-range data ships with the order.

OEM/ODM and factory-direct: what owning the line unlocks

Most NFC brands in Europe and North America already buy from Shenzhen and add a margin on the way to you; buying factory-direct simply removes the middle. Owning the line is also what makes real OEM/ODM possible — your brand on the tag, your antenna tuned to your surface, your encoding scheme locked on the traveler — instead of a logo printed on someone's stock part. For a worked example, see NFC brand authentication.

• OEM and ODM white-label — we manufacture under your brand with your artwork and packaging, or develop a tag to your functional spec from scratch; no Proud Tek marking appears unless you want it.
• Full customization — antenna size and shape, chip selection, substrate, adhesive, printing, encoding and packaging are all specified by you, because we control every step that sets them.
• Custom antenna and inlay development — where a catalogue inlay will not tune to your surface (glass, metal, a curved bottle), our RF engineers design and prototype a new antenna against your real material.
• Export logistics handled — DDP or FOB worldwide from Shenzhen near Hong Kong port, with the customs paperwork and certifications included, not billed as an extra.

Verify the factory before you commit

Trust on a first NFC order is not a feeling; it is a stack of records your supplier-qualification team can check without us in the room. Everything below is verifiable before you commit — the certifications page shows each standard and how to confirm it with the registrar, and the factory page documents the plant behind the tags.

• ✓ISO 9001, ISO 14001 and ISO 45001 certificates — certificate number and issuing registrar provided on request for independent verification.
• ✓Genuine-silicon proof: NTAG and ICODE parts carry an NXP originality signature you can verify on your own reader, so the chip in the tag is the chip on the quote.
• ✓100% functional read test on every encoded unit, with a batch report showing chip response, resonance frequency and read-range data.
• ✓Per-shipment documentation pack — Certificate of Conformity plus RoHS, REACH SVHC, CE and FCC declarations by SKU.
• ✓Open factory audits across two Shenzhen sites by appointment, with virtual walk-throughs and third-party (SGS, TUV, Intertek) inspection accommodated when a program requires it.
• ✓Quality records — encoding logs, read-test data and production travelers — retained seven years under ISO 9001, traceable by SKU or encoding lot.
