Patent Images
1. A process of forming a tactile dot group in a plastic card or a passport, the tactile dot group having two or more tactile dots arranged to form a tactilely recognizable character, comprising:
- embossing a first one of the tactile dots of the tactile dot group in a first column on the plastic card or passport using a punch and a die that has a single punch hole, the single punch hole of the die is defined by a center, a planar lip surrounding the single punch hole, and sloped walls surrounding and adjoining the planar lip;
after the first tactile dot is formed, embossing a second one of the tactile dots of the tactile dot group in the first column on the plastic card or passport using the punch and the die;
the first tactile dot and the second tactile dot of the tactile dot group are part of a tactile identifier mark that forms personal information of a holder of the plastic card or passport, and the plastic card or passport is a personalized plastic card or a personalized passport.

Abstract
Techniques are described for the production of tactile dots, tactile dot groups, and tactile identifier marks on substrates that are tactilely recognizable by visually impaired individuals. Each tactile dot can be formed individually in the substrate, for example by separately embossing each tactile dot using a single punch and die pair. By using a single punch and die pair, the size, complexity and cost of the tactile dot embossing mechanism can be reduced, and the spacing between the tactile dots can be varied.
