Introduction to NFC tags for guard control systems
NFC tags play a central role in modern guard tour systems. They enable reliable and efficient documentation of patrol routes. However, not every NFC tag is equally suitable for this purpose.
Requirements for NFC tags for guard control systems
The following criteria should be considered when selecting the right NFC tags for guard control systems:
- Durability: The tags must withstand extreme weather conditions.
- Durability: A long service life is essential for continuous use.
- Readability: Reliable data capture even under difficult conditions
- Mounting options: Secure mounting on various surfaces
- On-metal capability: Functionality on metallic surfaces
Recommended NFC tag types
1. On-Metal NFC Tags – The most important requirement
In practice, many control points are attached to metallic surfaces or the surfaces are metal-coated. Standard NFC tags do not work reliably or at all on metal because the metal interferes with the radio waves.
Therefore, it is essential to use special on-metal NFC tags. These tags are equipped with a special ferrite layer that compensates for interference from metal and ensures reliable readability even on metallic surfaces.
Typical metallic surfaces in guard control systems:
- Steel doors and gates
- Metal fences and railings
- Control cabinets and electrical distribution systems
- Machinery and equipment
- Metal cladding on buildings
2. Weatherproof NFC tags
Tags specifically designed for outdoor use with IP67 or IP68 protection ratings offer optimal protection against moisture and dust. These are ideal for checkpoints outdoors or in damp environments.
3. Industrial NFC Tags
These robust tags are designed for use in harsh environments and can withstand mechanical stress. They are particularly suitable for production halls, construction sites, or other demanding locations.
4. Compact Standard NFC Tags
For guard tour systems, the standard storage capacity is usually perfectly sufficient, as only a unique ID is needed to identify the checkpoint. These tags are cost-effective and reliable.
Conclusion
Choosing the right NFC tag is crucial for the reliability of your guard tour system. Pay particular attention to on-metal compatibility , as most checkpoints are mounted on metallic surfaces. Invest in high-quality, weather-resistant on-metal tags that meet the specific requirements of your operating environment.
