8.1.24.1 RSS-14 Standard
RSS-14 is capable of encoding up to 20 trillion values. There are actually 15 characters
that make up the barcode, but only 13 data characters and 1 check are encoded. The first
character is a flag, which determines if there is a Composite 2D barcode associated with the
barcode. This is the first character encoded and it should not be included in the "Data To
Encode" field.
The next 14 characters are the 13 data characters plus an implied check digit. The check
digit is not actually encoded in the barcode, but should be included as part of the "Data To
Encode" field.
If less than 14 characters are entered in the "Data To Encode" field, zeroes are padded to
the front after the linkage flag. Non-numeric characters are stripped from the "Data To
Encode" field.
8.1.24.2 RSS-14 Truncated
RSS-14 Truncated has the exact same data characteristics as the RSS-14 Standard
barcode, except the bar height is set to the RSS standard of 13 times the X dimension. This
symbology may be scanned omni-directionally.
The sample below is encoding this data string:
8.1.24.3 RSS-14 Stacked
RSS-14 Stacked has the exact same data characteristics as the Standard RSS-14 barcode.
The data to encode is split in half and encoded as a split level barcode. This format is used
if the width of the barcode will be an issue. The height of the top row of the RSS-14
Stacked barcode is 5 time the X dimension and height of the bottom row is 7 times the X
dimension. The barcode contains a separator pattern, containing no data, which has a
height equal to one X dimension. This symbology can not be scanned omni-directionally.
This symbology does not allow for human readable test with the barcode.
