Since then, the Belgian government has undertaken a long, involved process of tendering for voting systems by sections of the country. One of the problems the team faced was the huge number of candidates vying for each available office. As many as 100 candidates have been known to run for a single seat. By pressing the pen to the appropriate box, a black circle appears to the right of the name, indicating that candidate has been chosen by the voter. The voter then has the option of changing his or her vote, or confirming the choice and moving on to the next screen, and the next vote.
Touch screens leave a smear from fingertips, possibly giving indications of previous voting trends.
The light pen, on the other hand, most resembles the pencil to paper system all voters know and understand, regardless of their literacy or language. It requires no special training or co-ordination, and leaves no mark. Its three chip interface set, planted right on the motherboard, allowed for the highest resolution with the least amount of computer real estate consumed. The small number of parts also meant a smaller overall cost, and all of these factors together with dZine made a team that hopes will be a trend to electronic voting. While dZine is building its reputation as the leading expert on voting systems, it is very busy elsewhere.
