What Are RFID Hard Tags?
RFID Hard Tags are encapsulated in rigid or durable materials that protect the internal chip and antenna from harsh conditions. These tags are engineered to endure environments with extreme temperatures, high humidity, chemical exposure, and physical impacts. Their robust construction ensures that the RFID system remains effective and reliable under tough conditions.
Advantages of RFID Hard Tags
Feature | Description |
Durability | Encapsulation protects against physical damage and environmental factors. |
Temperature Resistance | Operate effectively in high and low temperatures. |
Chemical Resistance | Designed to resist exposure to chemicals and corrosive substances. |
Impact Resistance | Suitable for environments with rough handling and mechanical stress. |
Applications of RFID Hard Tags
RFID Hard Tags are essential in numerous industries due to their ability to perform reliably in adverse conditions. Here’s a look at their key applications:
Asset Management
RFID Hard Tags are crucial for tracking valuable assets in industries such as manufacturing and construction. They ensure accurate monitoring of tools, machinery, and equipment, helping to minimize losses and optimize operations.
Logistics and Supply Chain
In logistics, RFID Hard Tags facilitate the efficient tracking of goods through various stages of transportation and storage. Their robustness ensures that they can withstand the rigors of handling and environmental conditions, providing reliable data for supply chain management.
Industrial Laundries
Industrial laundries often operate at high temperatures and with aggressive chemicals. RFID Hard Tags used in these environments are coated to protect them from damage, ensuring they remain functional despite constant exposure to water and heat.
Animal Identification
RFID Hard Tags are employed in the identification of livestock, aiding in food safety and animal management. These tags provide accurate tracking throughout an animal’s life, even in challenging conditions.
Returnable Transport Items (RTIs)
For businesses managing returnable transport items, RFID Hard Tags offer a cost-effective solution. They help in tracking RTIs, reducing costs associated with losses and inefficiencies.
Hostile Environments
In environments with extreme conditions, such as high chemical exposure or severe temperatures, RFID Hard Tags ensure reliable tracking and monitoring, proving their versatility and durability.
Frequency Variations of RFID Hard Tags
RFID Hard Tags operate at different frequencies, each suited to specific applications. Understanding these frequencies helps in selecting the right tag for various use cases.
UHF RFID Hard Tags
Operating in the 860-960 MHz range, UHF tags are ideal for long-range applications such as warehouse management and vehicle access control. Their ability to read multiple tags simultaneously enhances efficiency in large-scale environments.
HF RFID Hard Tags
HF tags, functioning at 13.56 MHz, are used for applications requiring closer proximity. Common in libraries and public transportation systems, they are valued for their precision in short-range interactions.
LF RFID Hard Tags
Operating between 125 and 134 kHz, LF tags are suitable for applications where proximity and accuracy are crucial, such as animal identification and controlled access systems
