Appendix C: Tactile Identifier
Mark Conversion
Embosser font 11 allows you to emboss up to three braille (Tactile Identifier Mark or TIM)
characters on a card. Braille uses a 6-dot format to represent letters, numbers, and combinations
of sounds.
The braille characters are expressed as a sequence of numbers that indicate the position of the
dots, with dots 1–3 in the left column, and dots 4–6 in the right column.
The CE system uses a single emboss character to form each dot. Up to three 6-dot characters can
be embossed in any allowed location on the card.
The vertical and horizontal spacing between the embossed dots is 0.091 in (2.3 mm). The
distance between characters is 0.240 in (6.1 mm).
Because there is not a one-to-one correlation between the ASCII value and the braille character,
use the following conversion table to map your ASCII data to the braille characters. The table
includes the dot sequence for each character and its binary representation.
Some characters must be sent as an ASCII sequence because they are reserved XML
characters. In addition, some characters have more than one valid value. All are
shown in the following table.
