125KHZ+860-960Mhz UHF RFID Dual Frequecy ISO Card

Introduction

The 125KHz + 860–960MHz UHF RFID Dual Frequency ISO Card is a powerful hybrid identification solution that combines low-frequency (LF) proximity technology with ultra-high-frequency (UHF) long-range RFID in a single ISO-standard PVC card. By integrating a 125KHz TK4100 chip (read-only) and a UHF EPC Gen2 (Alien H3) chip, this card enables seamless interoperability between legacy access control systems and modern RFID tracking infrastructures.

This dual-frequency card is designed to bridge the gap between short-range secure identification and long-range automated tracking, making it highly valuable in industries transitioning from traditional RFID systems to advanced IoT-enabled environments.

If you’ve ever wished one card could open doors and announce your arrival from across the room—this is that card.

What Is a Dual Frequency RFID Card (125KHz + UHF)?

A dual frequency RFID card is a smart card embedded with two independent chips and antennas, each operating at different frequencies:

• 125KHz (LF) → Short-range proximity identification (read-only)
• 860–960MHz (UHF) → Long-range, high-speed RFID communication

This design allows the card to interact with both legacy LF readers and modern UHF systems, making it ideal for organizations upgrading their infrastructure without replacing existing systems.

Technical Specifications Overview

General Parameters

LF Chip (TK4100)

UHF Chip (Alien H3)

Working Principle

The card operates using two independent RFID systems, each activated by its corresponding reader.

1. LF (125KHz) Operation

• Reader emits low-frequency signal
• TK4100 chip is energized
• Card transmits its unique ID
• Used for access control and attendance

2. UHF (860–960MHz) Operation

• Reader emits UHF signal
• Alien H3 chip is powered
• Data is transmitted via backscatter
• Used for long-range identification

Dual Functionality in Practice

A single card can:

• Unlock doors at close range (LF)
• Be tracked automatically at a distance (UHF)

No switching, no user action—just seamless operation.
