Active Tags

Active RFID Tags, Active Communication

An RFID tag becomes active when it is equipped with a battery to provide a partial or complete source of power for the tag’s circuitry and antenna. Some active tags contain replaceable batteries, which can last for years, while others contain sealed units. In some cases it is also possible to connect the tag to an external power source.

Advantages:
We can provide RFID tags with reading distances of more than one hundred feet, greatly improving the utility and range of the device. It may have other electrically powered sensors that draw on external energy supplies.

Benefits:

• The longest communication range of any tag;
• Capability to perform independent monitoring and control;
• Can autonomously initiate communications;
• Capable of performing diagnostics;
• The highest data bandwidth available.

Active RFID Tags may even be equipped with autonomous networking to determine the best communication path available. Please send email to us if you have questions about Active RFID tag.

Difference between Active RFID Tags and Passive RFID Tags 

Active RFID and Passive RFID are fundamentally different technologies that are often grouped together. While both use radio frequencies to communicate between a ‘tag’ and a ‘reader’, the method of powering these tags is different.

Active RFID uses an internal power source(battery) within the tag to provide continuous power and its RF communication circuitry, while Passive RFID relies on RF energy transferred from the reader to the tag to power the unit.
