The scanning distance for RFID (Radio-Frequency Identification) can vary widely depending on several factors, including the type of RFID technology (LF, HF, or UHF), the power of the reader, the sensitivity of the tags, and the environmental conditions. Here’s a general overview:
1. Low Frequency (LF) RFID:
- Read Range: Typically between 10 cm to 30 cm (about 4 inches to 12 inches).
- Commonly used for applications such as animal tracking and access control.
2. High Frequency (HF) RFID:
- Read Range: Generally up to 1 meter (about 3 feet), but typically around 10 cm to 30 cm (4 inches to 12 inches).
- Frequently used in access control, payments, and library systems.
3. Ultra-High Frequency (UHF) RFID:
- Read Range: Can vary from 1 meter to over 12 meters (3 feet to over 39 feet), depending on the system design and environment.
- Often used in supply chain management, inventory tracking, and vehicle identification.
The actual performance can be affected by factors such as antenna design, tag orientation, interference from materials or other electronic devices, and atmospheric conditions. For precise applications, it’s recommended to refer to the specific
RFID reader and tag specifications.
