EPCElectronic Product Code

An identifier for a physical object, represented in formats defined by GS1. An EPC identifies; it does not by itself prove authenticity.Primary reference ↗

TIDTag Identifier memory

A Gen2 memory bank containing tag chip identification information. Serialisation and available fields depend on the chip and specification.Primary reference ↗

GTINGlobal Trade Item Number

A GS1 identifier for a trade item. A GTIN alone identifies the item class, not every individual physical instance.Primary reference ↗

SGTINSerialized Global Trade Item Number

Combines trade item identity with a serial number to distinguish individual instances.Primary reference ↗

SSCCSerial Shipping Container Code

A GS1 key used to identify a logistics unit, such as a pallet or parcel.Primary reference ↗

User memoryOptional application data

A tag memory bank that can hold application data. Availability and capacity depend on the tag IC.Primary reference ↗

EPCISVisibility event exchange

A GS1 standard for sharing events about identified objects, including the time, place and business context of an observation.Primary reference ↗

Read pointObservation location

In EPCIS, the location where an event occurred, which may be more specific than the business location.Primary reference ↗

Business stepProcess context

The business activity associated with an event, such as receiving or shipping. It adds meaning beyond a raw tag read.Primary reference ↗

DispositionBusiness condition

The business condition of an object following an event. It is distinct from its location or the operation being performed.Primary reference ↗

AggregationParent and child relationship

An EPCIS event can associate identified child objects with a parent, for example when items are packed into a case.Primary reference ↗

NFCNear Field Communication

A family of contactless interactions using a base frequency of 13.56 MHz, commonly designed around a deliberate tap.Primary reference ↗

NDEFNFC Data Exchange Format

A format for messages on NFC tags, with records describing content such as a web address or text.Primary reference ↗

Card emulationDevice acting as a contactless card

An NFC mode in which a device communicates with a reader as a contactless card, used in applications such as tickets and payments.Primary reference ↗

Reader / writerDevice interacting with a tag

An NFC operating mode in which a device reads data from, or writes data to, compatible tags.Primary reference ↗

RFIDRadio frequency identification

Identification using radio communication between a reader and a tag. Performance depends on the system and the object being identified.Primary reference ↗

RAIN RFIDPassive UHF RFID ecosystem

An industry name for passive UHF RFID systems based on the GS1 UHF Gen2 and ISO/IEC 18000-63 family of specifications.Primary reference ↗

Passive tagTag powered by the reader field

A tag that obtains energy for communication from the reader signal rather than an onboard transmitter battery.Primary reference ↗

InlayChip and antenna assembly

The chip and antenna assembly used as the core of an RFID label or another finished tag construction.Primary reference ↗

BackscatterModulated reflection

A passive UHF tag can communicate by changing how it reflects a reader signal, rather than generating its own carrier.Primary reference ↗

Check digitInput error check

A calculated digit used to detect some identifier entry errors. It does not validate the ownership or assignment of the number.Primary reference ↗

Wilson intervalUncertainty for a proportion

A confidence interval for a success proportion. Useful for interpreting a read test when the trial design supports a binomial model.Primary reference ↗
