HF vs. UHF RFID: What’s the Difference and Which One Should You Use?

🔍 RFID Technology Explained: HF vs UHF Frequency Bands

As IoT adoption grows rapidly, RFID technology has become essential for automated identification solutions across industries. But choosing between HF and UHF frequencies requires strategic consideration. In this comprehensive guide, we break down everything you need to know about these two critical RFID bands.

📡 What Are RFID Frequency Bands?

RFID systems operate on specific frequency ranges that determine their performance characteristics. The two most popular options are:

🆚 Key Differences at a Glance

💡 When to Choose HF RFID?

Opt for HF when you need:

• Secure access control systems
• NFC-compatible payments
• Medical patient tracking
• Library book management

🚚 When to Choose UHF RFID?

UHF is better for:

• High-volume inventory scanning
• Supply chain visibility
• Vehicle identification systems
• Retail anti-theftli>
