Amount of light returned from an illuminated surface.
The narrowest element dimension which is distinguished
by a particular reading device or printed with a particular
device or method.
Radio Frequency.
Radio Frequency Identification is a system for tagging and
identifying mobile objects such as store merchandise,
postal packages and sometimes living organisms (like
pets). Using a special device called an RFID reader, RFID
allows objects to be labeled and tracked as they move from
place to place.
Device used to read RFID tags.
Read-Only Memory. Data stored in ROM cannot be changed
or removed.
The name of the licensed Disk Operating System loaded
into the mobile computer's flash file system.
A device that connects networks and supports the required
protocols for packet filtering. Routers are typically used to
extend the range of cabling and to organize the topology of
a network into subnets. See Subnet.
An Electronic Industries Association (EIA) standard that
defines the connector, connector pins, and signals used to
transfer data serially from one device to another.
Area intended to contain a symbol.
An electronic device used to scan bar code symbols and
produce a digitized pattern that corresponds to the bars and
spaces of the symbol. Its three main components are:
1. Light source (laser or photoelectric cell) - illuminates a
bar code.
2. Photodetector - registers the difference in reflected light
(more light reflected from spaces).
3. Signal conditioning circuit - transforms optical detector
output into a digitized bar pattern.
The scanner is energized, programmed and ready to read a
bar code.
A method of programming or configuring parameters for a
bar code reading system by scanning bar code menus.
