programmer – tag contents can be changed by a set of electronics
in close proximity or in electrical contact with them; those electronics
and their packaging are called a
programmer
RFID – systems that read or write data to RF (radio frequency) tags
that are present in a radio frequency field projected from RF
reading/writing equipment; data may be contained in one or more
bits for the purpose of providing identification and other information
relevant to the object the tag is attached to; it uses electromagnetic
or electrostatic coupling in the radio frequency portion of the
spectrum to communicate to or from a tag through a variety of
modulation and encodation schemes
range – distance at which successful reading and/or writing can be
attained
read – decoding, extraction and presentation of data from
formatting, control and error management bits sent from a tag
readability – ability to extract data under less than optimal
conditions
read rate – maximum rate at which data can be read from a tag,
expressed in bits or bytes per second
read/write – many applications require that new data, or revisions to
data already in the tag, be entered into the tag while it is still
attached to its object; tags with this capability are said to be
reprogrammable and are called
read/write tags, memory cards, or
memory modules
reader – device containing the digital electronics that extract and
separate the information from the format definition and error
management bits; digital electronics perform the actual reading
function; these read electronics may also interface to an integral
display and/or provide a parallel or serial communications interface
to a host computer or industrial controller
reader/writer – the set of electronics can change the contents of the
tags while they are still attached to their object; they are called the
reader/writer (see reader )
reprogrammable – many applications require that new data, or
revisions to data already in the tag, be entered into the tag while it is
still attached to its object; the ability to read from and write data to
the tag while it is attached to its object is called
in-use
programming ; tags with this capability are said to be
reprogrammable and are called r ead/write tags, memory cards, or
memory modules
