Abstract
The present invention relates to the field of pocket-size electronic devices, including credit card sized devices such as authentication tokens. It consists of an improvement of the well-known “raised ridge” to protect individual buttons from false key presses, obtained by applying embossing. A known problem with applying embossing to cards containing electronic components, is the fact that the embossing process may damage the components or the wiring inside the card. In the process according to the invention, an embossed ridge of a judiciously designed shape is used to avoid such damage.
