How to Choose the Right RFID Labels for Your Project?
1. Identify and Assess the Tagging Surface:
- Metal and liquid surfaces: These materials could reflect or absorb radio waves, reducing the performance of RFID labels.
- Size and shape of the surface: For small or irregular surfaces, choose miniaturized or custom-shaped RFID labels with specialized adhesives for better performance.
2. Consider Environmental Conditions:
- Weather Conditions: RFID labels should withstand rain, humidity, UV exposure, or other weather elements when used outdoors.
- Temperature Conditions: When being in the process with extreme temperatures, specialized RFID labels are needed. RFID labels are suitable for managing trays in labs or for use in long, narrow surfaces like those found in cold storage environments.
- Harsh Physical Conditions: In environments with intense vibration, impacts, or rough handling, which are common in handling, transportation, and warehousing environments. Impact-resistant labels are essential to ensure reliable performance under harsh conditions.
3. Match the Read Range to the use cases:
The required read range varies with applications. For long-range tracking, RAIN RFID(UHF) labels are ideal, while HF or NFC labels work better for short-range, high-precision tasks.
4. Evaluate Security Requirement and Compliance:
RFID labels may store sensitive data, so encryption is vital to prevent unauthorized access, especially in high-security environments. Tamper-proof labels can detect and deactivate upon tampering. Additionally, compliance with industry regulations is crucial for ensuring data protection and regulatory adherence.
