Radio waves are invisible, but supply chains depend on them. Warehouses, gated communities, aviation logistics, retail inventory systems—these ecosystems quietly rely on UHF RFID technology to identify, track, and authenticate objects at scale.
The UHF 860–960MHz RFID Card built with Alien Higgs 3, Alien H4, or Impinj M5 chips represents a high-performance, long-range identification solution designed for industrial and commercial environments. It conforms to EPC Global Class 1 Gen 2 and ISO/IEC 18000-6C standards, enabling worldwide operation across the global UHF frequency spectrum.
This article provides a comprehensive overview of the product, including technical specifications, chip architecture, application scenarios, performance advantages, and how it solves real industry challenges.
Product Overview
This UHF ISO RFID card integrates an advanced UHF chip—commonly Alien Higgs 3 (H3), Alien H4, or Impinj M5—with a pre-encoded 64-bit unique identifier. Designed in standard ISO card size (85 × 54 mm), it combines long-range identification capabilities with the physical durability of a PVC card body.
Unlike HF (13.56 MHz) RFID cards used for short-range access control, UHF RFID cards operate in the 860–960 MHz band, enabling significantly longer read distances and faster bulk data processing.
If HF cards are like whispering at close range, UHF cards are like broadcasting across a room.

Understanding UHF RFID Technology (860–960 MHz)
UHF RFID operates at ultra-high frequencies between 860 MHz and 960 MHz, depending on regional regulations:
- 902–928 MHz (North America)
- 865–868 MHz (Europe)
- 920–925 MHz (Asia)
The EPC Gen2 protocol enables:
- Fast anti-collision processing
- Multiple tag reading
- Global interoperability
- High-speed data transfer
Unlike low-frequency (LF) or high-frequency (HF) cards, UHF cards support longer read ranges and bulk scanning, which is essential in logistics and asset tracking environments.
Chip Architecture: Alien H3, H4, and Impinj M5
Alien Higgs 3 (H3)
- 512-bit memory
- 64-bit unique ID
- Strong EPC memory structure
- High reliability in supply chain use
Alien Higgs 4 (H4)
- Improved sensitivity
- Better read performance
- Lower power consumption
- Enhanced encoding speed
Impinj M5
- Stable RF performance
- Good read accuracy
- Reliable anti-collision capabilities
These chips support read/write functionality, allowing users to encode EPC data or custom information.
The 64-bit UID is factory-programmed and cannot be altered, ensuring unique identity integrity.
In identification systems, uniqueness is everything. Two identical objects with identical IDs create chaos.
Primary Applications
1. Access Control (Vehicle & Long-Range Entry)
UHF RFID cards are ideal for vehicle access control systems. Drivers can hold the card near the windshield, and readers installed at gates detect the card automatically.
Applications include:
- Parking garages
- Residential compounds
- Industrial facilities
- Campus vehicle management
Compared to HF cards, UHF enables greater convenience and faster throughput.
2. Attendance Control
UHF RFID cards streamline attendance management in:
- Factories
- Large enterprises
- Schools
- Construction sites
Multiple employees can be identified quickly without direct card-to-reader contact.
3. Identification Systems
UHF cards serve as:
- Staff ID badges
- Contractor access passes
- Temporary visitor credentials
Longer read distance reduces bottlenecks in high-traffic environments.
4. Ticketing Systems
