RFID Tag's Classification by Frequency Bands

Passive RFID: Comparison by frequency bands

RFID systems operate in different frequency bands, each with its characteristics:

Low Frequency (LF, 125-134 KHz): Used for short-range applications (up to 10 cm). Common in animal tracking and access control.
High Frequency (HF, 13.56 MHz): Medium range (up to 60 cm) and commonly used in smart cards, ticketing, and library systems.
Ultra-High Frequency (UHF, 860-960 MHz): Longer range (up to 20 meters) and used in inventory management, supply chain, and logistics.

Frequency Bands	LF	HF	UHF
Frequency Bands	125-134 KHz	13.56 MHz	860-960 MHz
Read Distance	up to 10 cm	up to 60 cm	up to 20 meters
General Characteristics	Limited read range Performs well around liquids and metals Reliable in challenging environments Minimal interference from other electronic devices‌	Moderate read range Faster data transfer than LF Ideal for applications involving multiple tags at once (anti-collision capabilities)‌	Long read range Fast data transfer rate Capable of reading multiple tags simultaneously Suitable for large-scale, industrial environments‌
Cost	Highest	Low	Lowest
Read Speed	Slower←——————————————————————————————————→Faster
Environmental Impact	Not sensitive←———————————————————————————————→Highly sensitive

Choosing the right RFID frequency—whether LF, HF, or UHF—is crucial for the efficiency and effectiveness of your RFID system. Each frequency band offers unique advantages and is suited to specific applications. By carefully considering your environmental conditions, required read range, and interference factors, you can select the optimal frequency for your project.

With the right frequency in place, your RFID solution can streamline operations, enhance efficiency, and ultimately drive better business results.

This is the first one.
