They are the ultimate solution for asset tracking, vehicle access control, retail inventory management, and supply chain logistics. Take advantage of our factory-direct OEM/ODM pricing, custom printing, and bulk encoding services with an MOQ starting at just 1,000 pcs.

NXP UCODE Series — Long-Range EPC Gen2 UHF RFID Cards

Unlike standard NFC cards that require a close tap, UHF RFID cards are designed for distance and speed. The NXP UCODE family represents the pinnacle of passive UHF technology, allowing hundreds of tags to be read simultaneously at a distance without direct line-of-sight. This makes them indispensable for automated warehouse tracking and hands-free parking lot access control.

UCODE Chip Selection Guide

We supply and encode blank or custom-printed UHF cards utilizing the exact NXP UCODE silicon required for your specific tracking ecosystem:

• UCODE 8 / 8m: The industry standard for basic inventory management and retail apparel tagging. Highly sensitive and cost-effective, providing excellent global performance for mass EPC Gen2 deployments. (UCODE 8m includes an additional 32-bit user memory).
• UCODE G2iM / G2iM+: The workhorse for logistics, supply chain visibility, and asset tracking. Offers extended user memory (up to 640-bit) to store maintenance records, batch numbers, and detailed shipping data directly on the chip.
• UCODE DNA: The highest security UHF chip available. Features AES-128 cryptographic authentication to prevent tag cloning. Essential for secure vehicle access control, high-value asset tracking, and luxury brand anti-counterfeiting.

Top B2B Industry Applications

• Vehicle Access Control: Long-range hands-free gate access for parking lots, gated communities, and tolling systems.
• Asset Management & Tracking: Automated tracking of IT equipment, returnable transport items (RTIs), and high-value corporate assets.
• Logistics & Supply Chain: Bulk scanning of pallets and cartons in warehouse environments without unpacking.
• Retail Inventory: High-speed stock counting and supply chain visibility for the apparel and FMCG sectors.
• Brand Protection: UCODE DNA AES-128 cryptographic authentication for high-end luxury goods and pharmaceuticals.

Frequently Asked Questions (FAQ)

Q1. What is the difference between UHF RFID and NFC/HF RFID?

NFC and HF RFID (like MIFARE) operate at 13.56MHz and have a very short read range (2-10 cm), requiring the user to "tap" the card. UHF RFID (UCODE) operates at 860-960MHz, allowing for long-range reading (up to 8+ meters) and the ability to scan hundreds of cards or tags simultaneously. It is designed for hands-free tracking and logistics, not consumer smartphone tapping.

Q2. Can I use these cards for hands-free parking lot access?

Yes. UCODE cards are the industry standard for long-range vehicle access control. When paired with a compatible UHF gate reader, drivers can enter a parking facility without rolling down their windows to tap a badge.

Q3. Which UCODE chip is best for high-security applications?

If you are tracking highly sensitive assets or need secure vehicle access where cloning is a concern, we strictly recommend the UCODE DNA. It utilizes AES-128 cryptographic authentication, providing cryptographic proof of the tag's authenticity.

Q4. Can you make a single card that opens the parking gate (UHF) and the office door (HF)?

Yes. As an OEM manufacturer, we specialize in Dual-Frequency (Hybrid) Smart Cards. We can embed an NXP UCODE chip (for long-range parking access) alongside an NXP MIFARE DESFire or Classic chip (for standard door locks) within a single CR80 PVC card.

Q5. Do you provide bulk EPC encoding services?

Absolutely. We offer high-speed, automated EPC memory encoding based on your provided Excel/CSV database. We can also print the corresponding human-readable serial numbers, QR codes, or barcodes on the card's surface.
