Scanner

An electronic device that converts printed information into electrical signals.

Scan Reflectance Profile

A record (usually graphically represented) of the reflectance measured using the refer-

ence reflectivity method as a function of distance across the entire barcode symbol.

Segment

Refers to the left and right grouping of modules or elements into segments to designate

parity for checking validity of a scan.

Self-checking

A barcode or symbol that uses a checking algorithm, that can be applied to each character, to

guard against undetected errors. (Non-self-checked codes may use a check digit or other redun-

dancy in addition to the data message.)

Show-through

The generally undesirable property of a substrate that allows underlying markings of ma-

terials to affect reflectance.

Space

The element of a barcode symbol whose reflectance is greater than the global threshold.

A Space is the light reflective element. (As opposed to a bar which is the dark reflective

element.)

Space Reflectance (Rs)

Reflectance of a space.
