Extended Capability RFID

Extended Capability RFID . [http://www.itrportal.com/absolutenm/templates/article-barcode.aspx?articleid=5098&zoneid=6 "RFID and Extended Capabilities", "IT Reseller", July 28 2008] ] is a category of RFID that goes beyond the basic capabilities of standard RFID. Extended capability RFID provides the ability to read at longer distances and around challenging environments, to store large amounts of data on the tag, to integrate with sensors, and to communicate with external devices.

Examples of extended capability RFID tag technologies include EPC C1G2 with extended memory (e.g. 64Kb), battery-assisted passive, and active RFID. Battery-assisted passive, also known as semi-passive or semi-active, has the ability to extend the read range of standard passive technologies to well over 50 meters.

Also, battery-assisted passive only transmits a signal when interrogated, thus extending battery life. Active RFID, which can have some of the features of battery-assisted passive, is commonly used for even longer distances and real time locating. It also actively transmits a signal, which often results in shorter battery life.

Common applications of extended capability RFID include Yard Management, Parts Maintenance and Repair Operations, Cold Chain Management, Reusable Transport Items tracking, High Value/High Security Asset tracking, and other applications where extended capabilities are needed.
