WHAT IS
BARCODE SYMBOLOGY?

4. BARCODE
SYMBOLOGY
Is the method of encoding
data with dots, spaced lines, or
squares
Two types of barcode
symbology: discrete and
continuous

5. DISCRETE
VS.
CONTINUOUS Each character on a
single barcode can
be read together
s.
Continous
Each character on a
barcode can be
decoded
independently
Discrete

SIZE OF BARCODES

7. BARCODE SIZES
Two-width symbology applies
to barcodes with only two
possible bar sizes
Multiple-width symbology
provides for 3 alternative bar
widths as opposed to simply
two (1x, 2x, 3x)
