An RFID tag that has a transmitter to send back information, rather than reflecting back a signal from the reader, as a passive tag does. Most active tags use a battery to transmit a signal to a reader. However, some tags can gather energy from other sources. Active tags can be read from 300 feet (100 meters) or more, but they're expensive (typically more than US$20 each). They're used for tracking expensive items over long ranges. For instance, the U.S. military uses active tags to track containers of supplies arriving in ports.
An RFID tag that has a transmitter to send back information rather than reflecting back a signal from the reader like passive tags do. Most active tags use batteries as a partial or complete source of power to transmit a signal back tot he reader. Active tags can be read from long distances, but they're much more expensive than passive tags. They're mostly used for tracking expensive items over long ranges.
RFID tags with a battery or other integrated source of energy see Transponder.
An RF tag (transponder) that uses batteries as a partial or complete source of power. Batteries may be replaceable or sealed in. Active tags are more expensive and have much longer read ranges than passive tags. They are typically used to track expensive items over long ranges.
An RFID tag that has an on-board power supply. Active tags can communicate over long distances (up to 100 Metres).
Active Tags are radio frequency identification devices that require batteries for their operation.
An RFID tag that contains a battery and a transmitter to send information to an RFID reader, rather than reflecting a signal back to the reader from a tag (as a passive tag does).
An RFID tag that comes with a battery that is used to power the microchip's circuitry and transmit a signal to a reader. Active tags can be read from 100 feet or more away, but they're expensive – more than $20 each. They're used for tracking expensive items over long ranges. For instance, the US military uses active tags to track containers of supplies arriving in ports.
an RF tag powered by a battery. It has more memory and a longer radio range than a passive tag. Active tags are typically used in closed-loop applications.
