July 9, 2007—The European EPC Competence Center (EECC), in an effort to ease and speed the roll out of RFID, has performed standardized tests on 20 passive EPC UHF tags provided by six manufacturers. The results of the tests were published in a report designed to help companies compare tags easily and select the right RFID transponders for their products and applications. - l! q/ D0 h* t, e 0 @3 s: n- N8 f3 G: kThe 20 tag models were made by Alien Technologies, Avery Dennison, Checkpoint Systems, Impinj, KSW Microtec, Omron, RSI ID Technologies, Motorola (formerly Symbol) and UPM Raflatac. The EECC tested the tags' production consistency, orientation sensitivity, backscatter range (a measure of a tag's ability to reflect the energy it receives from an RFID interrogator) and read ranges in five attachment scenarios: unattached to any product (freestanding), attached to a 2-millimeter-thick layer of Teflon (simulating RF behavior when tags are affixed to paper products), fastened to a 10-millimeter-thick layer of Teflon (simulating the RF behavior of tags placed on plastic cases), attached to a plastic (PET) bottle of water and attached to a metal surface. To keep the test results reader-independent, the tags were tested in a controlled environment in an anechoic chamber using National Instruments test equipment running EECC's test software...
