Non-Rewritable LED Tag

RFID UHF (Ultra High Frequency) LED tag is a type of radio-frequency identification (RFID) tag that includes an LED (Light Emitting Diode) indicator. RFID UHF tags are commonly used for tracking and managing inventory, assets, and objects in various industries.

Here's how these tags work:

1. RFID UHF Technology: UHF RFID technology operates at a higher frequency range (typically 860-960 MHz) compared to traditional RFID systems, which allows for longer read ranges and faster data transfer.

2. Tag Communication: UHF RFID tags communicate with RFID readers or interrogators using radio waves. When a reader emits a signal, the UHF RFID tag receives the signal and uses the energy from it to transmit its unique identifier and, in the case of an LED tag, to power the LED indicator.

3. LED Indicator: The LED on the RFID UHF LED tag serves as a visual indicator. It can be programmed to light up in different colors, patterns, or sequences to provide information or status updates. For example, it may change color to signal that an item has been successfully scanned or to indicate low battery power.

Applications of RFID UHF LED tags include inventory management, asset tracking, supply chain management, and logistics. These tags can be used to monitor the movement of items in real-time, improving the accuracy and efficiency of data collection and management. The LED indicator adds a visual element that can help operators and users quickly assess the status of the tagged items.

Keep in mind that the specific features and capabilities of RFID UHF LED tags may vary by manufacturer and use case, so it's essential to consult with the manufacturer or supplier to determine the exact functionality and specifications of the tags you're interested in.
