Active tag: 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)...

Invisi-Tag® RFID

These frequencies determine what type of range the reader would detect RFID Tags. The RFID Reader sends enough radio waves to start the RFID tag's circuit. The activated tag then transmits the signal with an ASCII/Binary/EPC or other format of unique number. This unique serial number is related in a database to represent a product or information.

RFID Tags

RFID Tags are the receiver component of the system which receives the radio waves. The RFID tag is a crucial component of this system. There are two types of tags, active tags and passive tags.

Active Tags

An active tag has its own power source. The advantage of this particular tag is...
