Generating Quick Response Code in Software Glossary

EEPROM are more expensive than factory programmed tags that cannot be reprogrammed electromagnetic interference (EMI) Interference caused by radio waves of various RF-emitting devices such as cell phones, cordless phones, and microwaves EMI reduces the performance of an RFID system electronic article surveillance (EAS) A method of preventing unauthorized removal of articles from an area The system consists of gate antennas, readers, and EAS tags Tags are attached to the articles being monitored This system is widely used to prevent shoplifting in retail stores and pilferage of books from libraries The tags are turned off by the staff when items are properly removed If a tagged item is removed without the tag being deactivated, the detection system located at the exit reads the tag and sounds an alarm or alerts the staff electronic data interchange (EDI) in a standardized format A method of transmitting electronic data

electronic pedigree Collection of data about the movement of product through supply chain, which helps prevent product counterfeiting Electronic Product Code (EPC) A family of coding schemes designed by EPCglobal, Inc, to provide unique identification of objects in global trade The object can be a product, a container, a vessel, or a location EMI See electromagnetic interference

encryption A method of scrambling information to make it unreadable to those who are not authorized to read it In an RFID system, encryption prevents readers that are not part of the system from reading information stored on RFID tags enterprise resource planning (ERP) A business management multi-module software system that integrates (or attempt to integrate) all facets of the business, including planning, manufacturing, sales, and marketing into a unified system It integrates business activities such as product planning, purchasing, inventory control, order tracking, customer service, finance, and human resources All information is saved in a relational database system The deployment of an ERP system can involve considerable business process analysis, employee retraining, and new work procedures EPC See Electronic Product Code

EPC Discovery Service As a part of EPCglobal Network, allows users to find data related to a specific Electronic Product Code EPC Generation 2 (Gen 2) The standard ratified by EPCglobal for the air interface protocol for the second-generation of EPC technologies EPC Information Service A specification for a standard interface for accessing Electronic Product Code related information from EPCglobal Network It allows companies to store EPC data in secure databases on the Web EPCglobal, Inc A non-profit organization set up by the Uniform Code Council and EAN International, the two organizations that maintain barcode standards, to commercialize EPC technology EPCglobal is leading the development of industry-driven standards for EPC to support the use of RFID Uniform Code Council and EAN International are now part of an organization called GS1 EPCglobal Network A set of specifications that allows companies to collect, store, and retrieve data associated with Electronic Product Codes EPROM See erasable, programmable, read-only memory

erasable, programmable, read-only memory (EPROM) Nonvolatile memory that can be erased by exposing it to ultraviolet light and reprogrammed error correcting code Code stored on an RFID tag that enables localization and correction of errors error correcting mode Automatically detects and corrects errors in the data transmission between tags and readers ETSI See European Telecommunications Standards Institute

European Article Numbering (EAN) An industry organization that develops and maintains barcoding standards for product identification European Telecommunications Standards Institute (ETSI) An independent, non-profit telecommunications standards organization whose work is carried out by technical working groups consisting of telecommunications companies, manufacturers, regulatory authorities, and other parties in the sector excite An RFID reader excites (powers up) a passive tag by sending radio waves toward it The tag responds by transmitting a radio signal toward the reader
