Rfid card manufacturers

Buyers must first identify the operating frequency: Low Frequency (125 kHz) for basic access control, High Frequency (13.56 MHz) for secure payments and data exchange (e.g., Mifare chips), or Ultra-High Frequency (860-960 MHz) for long-range logistics. Additionally, verify the chip type (e.g., NXP, Fudan, or Impinj) and memory capacity (typically 1K, 4K, or 8K bits) to ensure compatibility with existing readers and software systems.

Request cards made from high-quality PVC, PET, or PC materials to prevent cracking and yellowing. For industrial environments, ensure the cards have an IP67 or IP68 waterproof rating. The lamination process should be seamless to protect the internal antenna from moisture and physical stress. Always ask for a bending test report to confirm the card can withstand daily use without antenna failure.

Ensure the products comply with ISO/IEC 14443 or ISO 15693 for proximity and vicinity cards. For security-sensitive projects, prioritize chips with AES-128 bit encryption or higher to prevent unauthorized cloning. If sourcing for the European or US markets, verify RoHS and REACH compliance to ensure the materials are free from hazardous substances.

Yes, professional suppliers on Made-in-China.com offer extensive customization. This includes CMYK offset printing, UV anti-counterfeiting marks, laser-engraved UID numbers, and magnetic stripes. For functional customization, you can request hybrid cards that combine two different chips (e.g., LF + HF) in a single card to bridge legacy and modern systems.

Implement a strict sampling protocol where the supplier provides a video of a random chip-reading test before shipment. Use third-party inspection services to verify the UID continuity and chip response rate. It is highly recommended to use Trade Resources or Secure Payment services on Made-in-China.com to ensure funds are only released after quality verification.

RFID cards are often classified under HS Code 8523.52. Ensure the supplier provides a Certificate of Origin to potentially reduce import tariffs. Because these items are lightweight but high-value, air freight or express couriers (DHL/FedEx) are usually the most cost-effective and secure methods. Ensure the packaging includes anti-static shielding to prevent electromagnetic interference during transit.

Pricing is heavily dependent on chip market fluctuations. Negotiate a price validity period (e.g., 15-30 days) to protect against sudden chip shortages. For bulk orders exceeding 10,000 units, aim for a 15-20% discount compared to sample pricing. Standard lead times are 7-10 business days, but you should negotiate a penalty clause for delays exceeding two weeks to ensure project timelines are met.
