Electrostatic coupling
Systems which use the inducing of a voltage on a plate as a means of transferring data or
power are said to use electrostatic coupling.
Error
Any operation or data which is not in accord with the design or input to the system.
Error Correcting Code (ECC)
Supplemental bits in a data transfer used in conjunction with a polynomial algorithm, in
order to compute the value of missing or erroneous data bits (e.g. for a 32 bit data
transmission, 7 additional bits are required.)
Error Correcting Mode
Mode of data communication in which missing or erroneous bits are automatically
corrected.
Error Correcting Protocol
The rules by which the error correcting mode operates.
Error Management
Techniques used to ensure that only correct information is presented to the user of the
system.
Error Rate
The number of errors per number of transactions.
Exciter
The electronics which drive an antenna are called the exciter or transmitter. Together with
the antenna they are called a scanner.
Expansion Port
A plug accessing additional 1/0 capability on a computer or peripheral device.
Factory Programming
The programming of information into a tag occurring as part of the manufacturing process
resulting in a read only tag.
Field Programming
Programming information into the tags may occur after the tag has been shipped from the
manufacturer to an OEM customer or end user or in some cases to the manufacturer's
distribution locations. Field programming usually occurs before the tag is installed on the
object to be identified. This approach enables the introduction of data relevant to the
specifics of the application into the tag at any time; however, the tag would typically have
to be removed from its object. In some cases, change or duplication of all data in the tag is
possible. In other cases, some portion is reserved for factory programming. This might
include a unique tag serial number, for example.
