RFID Terminology

RFID Terminology

 Noun  Abbreviations  Definition
 Active tag
A class of RFID tag that contains a power source, such as a battery, to power the microchip’s circuitry.
Active tags transmit a signal to a reader and can be read from 100 feet or more away. This class of tag is also known as a battery-assisted tag.

Advance Ship Notice

 ASN

The Electronic Data Interchange (EDI) transaction that provides the receiving company with advance data on shipments to better plan workloads and receipt processing.
In the implementation of the transaction, the latest the ship notice may be sent is the time of shipment. In practice, the ship notice must arrive before the shipment.

 Air interface The radio frequency link between a reader and RFID tags.
Amplitude

Modulation

 AM Representation of data or signal states by the amplitude of a fixed frequency sinusoidal carrier wave. Where data is in binary form the modulation involves two levels of amplitude and is referred to as Amplitude Shift Keying (ASK).
 Antenna The conductive element that enables an RFID tag or tags to send and receive data.

 Amplitude Shift

Keying 

 ASK

Representation of binary data states, 0 and 1, by the amplitude of a fixed frequency sinusoidal carrier wave. Where the amplitudes are determined by the carrier being switched on and off, the process is known as On-Off Keying (OOK).

 Auto-ID Center

The Auto-ID Center officially closed on October 26th, 2003. Its work was transferred to EPCglobal Inc. See Auto-ID Labs.
 Auto-ID Labs

The academic entity headquartered at Massachusetts Institute of Technology (MIT) chartered to research and develop EPCglobal Network technologies and applications. Visit www.autoidlabs.org.

 Automatic Identification

and Data Capture

Technology associated with the creation and acquisition of machine-readable data. The primary technologies are bar codes and Radio Frequency Identification (RFID).

Backscatter

Modulation

 A process whereby a transponder responds to a reader/interrogation signal or field by modulating and re-radiating or transmitting the response signal at the same carrier frequency.
 Bandwidth The range or band of frequencies, defined within the electromagnetic spectrum, that a system is capable of receiving or delivering.

 Carrier Frequency The frequency used to carry data by appropriate modulation of the carrier waveform, typically in a radio frequency identification system, by amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK) or associated variants.

 Channel 
A medium or medium associated allocation, such as

carrier frequency, for electronic communication.

 Discovery

Services

A component of the EPCglobal Network consisting of a suite of services that enable users to find data related to a specific Electronic Product Code (EPC) and to request access to that data. Object Naming Service (ONS) is one component of Discovery Services.
 EAN International EAN  EAN International, based in Brussels, Belgium, is an organization of EAN Member Organizations that co-manages the EAN.UCC System and Global Standards Management Process with the Uniform Code Council, Inc.R (UCCR).

 Electronic Data

Interchange

 EDI A standard format for computer-to-computer transmission of business information and transactions between trading partners, such as invoices and purchase orders.
 Electronic

Product Code™

 EPC The Electronic Product Code (EPC) is an identification scheme for universally identifying physical objects via Radio Frequency Identification (RFID) tags and other means. The standardized EPC data consists of an EPC (or EPC Identifier) that uniquely identifies an individual object, as well as an optional Filter Value when judged to be necessary to enable effective and efficient reading of the EPC tags.
 EPC Information

Services 

 EPC IS A component of the EPCglobal Network, which enables users to exchange EPC-related data with trading partners through the Network.

 EPC Middleware

EPC Middleware is the component of the EPCglobal Network that manages real-time read events and information, provides alerts, and manages the basic read information for communication to EPC

Information Services and a company’s other existing information systems. EPCglobal is developing a software interface standard for services enabling data exchange between an EPC reader or network of readers and information systems.

 EPC Manager Number Identifies the company or company entity.
 EPC reader
 EPC reader is an RFID reader that complies with the

EPCglobal standard.

EPCglobal Inc™

A joint venture between EAN International and the Uniform Code Council, Inc.R (UCCR). It is a not-for-profit organization entrusted by industry to establish and support the Electronic Product Code and the global adoption of the EPCglobal Network as the global standards for immediate, automatic and accurate identification of any item in the supply chain of any company, in any industry, in any country in the world.
