The '''Special - Barcode''' [[Custom Field]] displays a barcode, which is an optical machine-readable representation of data.
This field type converts another field's value (numeric or alphanumeric depends on the coding system selected) into a barcode image.
==Field Illustrated==
==Values==
The '''Values''' field is used to specify:
* The Custom Field ID of the field that contains the integer or text string you wish to have converted to a barcode.
* The Code Type (also known as Symbology), which is the encoding format of the barcode.
'''Notes on Code Types'''
Many of the Code Types listed above have strictly defined rules about the number of digits, location of alphanumeric characters etc. :::''For example: EAN13 requires 13 integers; RM4SCC is for UK Postal Codes, and cannot have any spaces.'':::If the Custom Field you are using as the source does not meet the requirements no barcode will be displayed.
