An Ultra High Frequency (UHF) NFC tag combines two distinct technologies: Ultra High Frequency (UHF) RFID and NFC (Near Field Communication). Here’s a breakdown of each component:
Ultra High Frequency (UHF) RFID:
UHF RFID operates at frequencies between 860 and 960 MHz.
It allows for longer read ranges compared to standard NFC tags, typically up to several meters depending on the power and antenna design.
UHF RFID tags are commonly used in supply chain management, inventory tracking, and logistics due to their longer range and ability to handle multiple tags simultaneously.
Near Field Communication (NFC):
NFC operates at 13.56 MHz and is designed for short-range communication (within a few centimeters).
NFC tags are often used in contactless payment systems, access control, and interactive marketing.
NFC tags are passive devices powered by the electromagnetic field generated by an NFC reader.
Combining these technologies into an UHF NFC tag brings together the longer read range capabilities of UHF RFID with the convenience and security features of NFC. This hybrid tag is useful in applications where both short-range interaction (such as mobile phone interaction) and longer-range identification or tracking (like asset management) are required.
Applications of UHF NFC tags include:
Asset Tracking: Tracking items or assets over a larger area than traditional NFC allows.
Supply Chain Management: Monitoring inventory throughout the supply chain with increased efficiency.
Access Control: Securely granting access to facilities or information using both NFC-enabled devices and UHF RFID readers.
Smart Packaging: Providing detailed product information or authentication via NFC while enabling tracking through UHF RFID in logistics.
In essence, an UHF NFC tag leverages the strengths of both technologies to create versatile solutions that cater to a wider range of use cases in various industries.
