RFID Manufacturer in Shenzhen

Two factories, ten lines: what runs on the floor

Proud Tek has manufactured RFID and NFC products in Shenzhen since 2008 — 18 years of continuous operation. Production runs across two factories with ten automated lines and more than 305 pieces of equipment, organized into six line families. Every value-added step happens in-house, and the operators who build a pilot lot are the same people who run the production order, which is why first-run defect rates tend to stay flat across a program's life.

• 2008Founded in Shenzhen
• 2Factories
• 10Automated production lines
• 305+Pieces of equipment

• Wet-inlay assembly: chip-to-antenna bonding for HF (13.56 MHz) and UHF (860-960 MHz) inlays on PET and PI substrates, with ESD-controlled stations and readability QC at the line.
• Card and label lamination: PVC, ABS, PETG, recycled-PVC and transparent stocks hot-roll laminated, with inlay placement held tight enough for reproducible DESFire and MIFARE Plus encoding.
• Anti-metal lamination: ferrite-backed inlays for on-metal asset, tool and equipment tags, with read range validated against steel and aluminum surfaces per SKU.
• Encoding and personalization: UID locking, NDEF programming, GS1 SGTIN-96, custom block writes and key diversification, including reel-to-reel encoding lines for high-volume UHF programs.
• Print and marking: four-color offset, screen printing, hot stamping, laser engraving for consecutive serialization, and variable-data inkjet for QR and barcode overlays.
• Final QC, packaging and warehouse: 100% functional read test on every encoded unit, AQL sampling on visual and dimensional attributes, packaging from bulk poly bag to branded retail box, and bonded warehousing for distributor safety stock.

Why factory-direct beats a trading company

Most international RFID buyers have dealt with at least one trading company reselling another factory's product at a markup, with no engineering recourse when read range or compliance problems surfaced. The difference is structural: a trading company cannot control a production process it does not own. Buying factory-direct removes the margin layer and, more importantly, connects your program to the people who actually build the product.

• Trading companies typically add 15-30% margin to factory pricing while owning no equipment. They cannot adjust a process, expedite a line or stand behind a quality claim with corrective action.
• Your purchase order goes to our production floor, not into an intermediary's queue with their suppliers — production schedule visibility comes straight from the planner.
• Engineering escalation is direct: chip-side or reader-range issues route to the inlay and encoding team that built the SKU, not a sales layer relaying messages.
• Pricing is transparent. Quotations can be broken down by cost component — chip, antenna, card body, printing, encoding and packaging — so specification trade-offs are visible before you commit.
• Compliance documents (RoHS, REACH, FCC, CE) ship with every order as a standard deliverable, not an upcharge or an unavailable extra.

OEM, ODM and solution-partner programs

Beyond catalog SKUs, Proud Tek runs OEM and ODM programs for system integrators, distributors and brand owners — we currently white-label for more than 100 brands across the 50+ countries we ship to, with strict confidentiality between competing customers. For applications where a standard product is not optimal, our RF engineers design custom antennas, select materials and engineer housings, then iterate prototypes until performance meets your specification.

• White-label by default: OEM packaging, branded boxes, sleeves or blister packs, custom product labels and private-label documentation, with NDAs available on request.
• Application consulting: we analyze your use case, environment, read requirements and budget to recommend the right technology (LF, HF, UHF, NFC), chip family and form factor before you spend on tooling.
• Custom development: RF antenna design, housing engineering, prototype production and performance testing — typically a 4-8 week cycle for tags or cards that do not exist in the catalog.
• Encoding and data services: pre-encoded data structures, UID databases, encoding-format design and key diversification so credentials arrive deployment-ready.
• Pilot support: small comparative lots of multiple candidate SKUs for field testing, with engineering support for read-range validation before any volume commitment.
• Supply continuity: once a solution is validated, recurring orders move onto scheduled deliveries and safety-stock programs, with the same account engineer staying on the program across years.

Quality system and compliance documentation

Procurement teams qualify factories on paperwork as much as on product, so the quality system is built to be audited. The facility is ISO 9001:2015 certified, quality records are retained for at least seven years, and every shipment leaves Shenzhen with the documentation buyers need at customs and at brand-owner intake. Buyer and third-party audits are welcome — they reduce procurement risk on both sides.

• 100% functional read test on every encoded unit, with a documented test report shipped with every order.
• AQL sampling on visual and dimensional attributes, with first-piece QC at line start and in-process checks logged on the production traveler.
• Per-shipment document pack: commercial invoice and packing list with chip family and encoding lot per line item, Certificate of Origin, radio-compliance Certificate of Conformity (FCC / CE / MIC / CCC as applicable) and RoHS / REACH SVHC material declarations.
• Quality records — travelers, encoding logs, QC results and material certificates — retained for at least seven years per ISO 9001 and retrievable by SKU code or encoding lot.
• Third-party audits accommodated: TÜV, SGS, Intertek, Bureau Veritas and BSCI / Sedex visits, plus buyer engineering audits and pre-shipment inspection in-house at no charge.
• Virtual factory tours: live video walk-throughs scheduled against your time zone for teams that cannot travel.

How programs start: samples, pilot, production

Most buyers move from first inquiry to first production order in three to six weeks, depending on how long samples sit in internal testing. We reply to inquiries within one business day, Monday to Friday (GMT+8), and free samples with RF test data come with every order — so supplier qualification costs stay on our side of the table, not yours.

• Step 1 — Inquiry and scoping: send your chip family or read requirements, form factor, environment, expected annual volume and compliance constraints; you receive a recommended SKU shortlist and indicative pricing within one business day.
• Step 2 — Sample qualification: a sampling kit (typically 50-100 encoded units across shortlisted SKUs) ships free for qualified B2B inquiries; most teams take one to two weeks to validate against their reader fleet.
• Step 3 — Pilot order: usually 5,000-50,000 pieces, with the encoding scheme, packaging spec and compliance documentation pack locked. Pilot lead time is typically two to three weeks once artwork and encoding files are signed off.
• Step 4 — Production rollout: reorders move on a 3-4 week cycle, or onto forecast-based safety-stock programs with call-off shipments dispatched within 3-5 business days of release authorization.
• Logistics: DHL / FedEx / EMS air freight or sea LCL / FCL on standard FOB Shenzhen / Yantian terms, shipping to more than 50 countries with full customs documentation.
