Security (Equal
Scans)
Calculated reading security for the transmitted bar-
code.
The specified value determines how often each
individual digit of the barcode must be extracted
from a scan, before it is declared as valid. Only
once this condition is fulfilled for all digits, the bar-
code decoding is acknowledged as being valid.
