What are the different types of RFID?

RFID systems are generally classified into three frequency ranges:

LF (Low Frequency, 125–134.2 kHz)

Suitable for access control, animal identification, and attendance systems. It offers a short reading distance but performs well around water and metal.

HF (High Frequency, 13.56 MHz)

Widely used for smart cards, library management, ticketing, cashless payment, and NFC applications. Typical reading distance is up to 10 cm.

UHF (Ultra High Frequency, 860–960 MHz)

Ideal for logistics, warehouse management, retail inventory, asset tracking, and industrial automation. Reading distance can reach over 10 meters under suitable conditions.
