Glossary of RFID Terms

If there is a term that should be in this glossary but isn't, please let us know by sending e-mail to .

L

Label applicator
A device that applies labels to cases or other items. Some label applicators can print bar codes on and encode RFID transponders in labels before applying the labels.
License plate
This term generally applies to a simple RFID that has only a serial number that is associated with information in a database. The Auto-ID Center promoted the concept as a way to simplify the tag and reduce the cost.
License plate tag
An RFID tag or other data carrier that contains a unique identifier for the physical object to which it is affixed, and no other business information. Other business information must be associated with the license plate identifier through an external database or other means.
Linear-polarized antenna
An antenna that focuses the radio energy from the reader in one orientation or polarity. This increases the read distance possible and can provide greater penetration through dense materials. Tags designed to be used with a linear polarized reader antenna must be aligned with the reader antenna in order to be read. (See circular-polarized antenna.)
LLRP Standard
A standard produced by the EPCglobal Reader Operations Working Group to foster RFID reader interoperability and create the foundation for technology providers to extend basic capabilities in satisfaction of industry-specific requirements. The LLRP standard is the result of collaboration between more than 90 end users, RFID infrastructure vendors, middleware vendors, industry experts and networking professionals.
Lossy
Characterized by or causing dissipation of energy. For instance, a cable is said to be a lossy cable if the signal attenuates as it travels through the cable.
Low-frequency
From 30 kHz to 300 kHz. Low-frequency tags typical operate at 125 kHz or 134 kHz. The main disadvantages of low-frequency tags are they have to be read from within three feet and the rate of data transfer is slow. But they are less subject to interference than UHF tags.
Low-Level Reader Protocol Standard
A standard produced by the EPCglobal Reader Operations Working Group to foster RFID reader interoperability and create the foundation for technology providers to extend basic capabilities in satisfaction of industry-specific requirements. The LLRP standard is the result of collaboration between more than 90 end users, RFID infrastructure vendors, middleware vendors, industry experts and networking professionals.
