Figure 218: Barcode Extended for QR Code

BarCode Extended for QR Code:

Enable ~: Allows to encode 3-digit decimal values. The format is ~d followed by 3 digits. This leads to a compression of the data because ~d will not be used and the following 3 digits as decimal number will be encoded by the according character in the ASCII-table. For example: ~d090 will be changed into 90 of the ASCII-table, e.g. the character Z

Barcode Mode: Choose the desired mode in the drop down menu. Options are 'Numeric', 'Alpha', 'Byte', and 'Kanji'.

Note that, depending on the selected mode, different types of characters are allowed. You will get direct feedback, via the 'Valid' checkbox (see Barcode).

In addition, the selected mode also changes the number of valid characters!
