Electronic
Product Code (EPC) is a unique number that identifies a specific item in
the supply chain. The EPC is stored on a radio frequency identification
(RFID) tag, which combines a silicon chip and an antenna.
Once the EPC
is retrieved from the tag, it can be associated with dynamic data such
as from where an item originated or the date of its production. Much
like a Global Trade Item Number (GTIN) or Vehicle Identification Number
(VIN), the EPC is the key that unlocks the power of the information
systems that are part of the EPCglobal Network.
Essentially, the EPC
is a number designed to uniquely identify a specific item in the supply
chain. The EPC number sits on a tag comprised of a silicon chip and an
antenna, which is attached to an item. Using radio identification
technology (RFID), a tag “communicates” its number to a reader.
EPCglobal Network
is a set of technologies that enable immediate, automatic identification
and sharing of information on items in the supply chain. In that way,
the EPCglobal Network will make organisations more effective by enabling
true visibility of information about items in the supply chain.
ID System (EPC
Tags and Readers) A label tag is a thin, consumable device with a
programmable microchip and an antenna. Data can be read and written with a
reader device, without a direct line of sight. Tags embedded inside labels
help solve problems in product identification, control, tracking and
security and can be used in a wide variety of applications.
Object Name Service
(ONS)
The reader passes the number to a computer or local application system, known as
the Object Name Service (ONS). ONS tells the computer systems where to
locate information on the network about the object carrying an
EPC, such
as when the item was produced.
Physical Markup Language (PML)
is used as a common language in the
EPCglobal Network to
define data on physical objects.
RFID stands for
radio
frequency identification. It is a technology that has existed for
decades. At a simple level, it is a technology that involves tags that
emit radio signals and devices called readers that pick up the signal.
RFID technology is a fundamental element of the
EPCglobal Network.
RFID ICs
are the tiny computer chips in the RFID labels.
Savant
is a software
technology that acts as the central nervous system of the
EPCglobal
Network. Savant manages and moves information in a way that does not
overload existing corporate and public networks.
