Karlijn;
from our experince at Campaign Cup, i would recomend that you don't make the marshalls responsible for Players cards. In fact the only thing the marshalls should really be focusing on is the actual game.
Instead we employed a person to check player IDs, and wrangle the players into the chrono area. We then had a second seperate Chrono Judge, who only did chrono and armbands.
The Chrono Judge even in some cases did the flip coin for sides. As soon as the judges shout game over, the next teams are sent strait onto the field, and strait to their relative start gates. The turn around could be less than 2 minutes!
As for checking Player IDs, the system could be done with a Palm Pilot system, and a barcode reader which is relativly cheap (compared to Laptops). But at the end of the day you still have to check the player's face against the pic on the card, so there's no real point in having a scanning system as there is no real benifit.
I don't know if it is public knowledge of what the money generated by the ID cards is used for, Karlijn, if it is, maybe you could explain who's wages it covers.
Just a quick word for all players who complain about paying for a players card;
This isn't some back woods paintball tournament you're attending, this is a world wide series. When you are playing tournaments of this calibre the series needs to regulate players. The millennium series is committed to making the team rosters fair, being able to ban cheating players, and making the players areas more secure. To do this, we need a system of idenitifying players. Having a players card is the only way we can achieve this.
If you don't care about banned players playing, players switching rosters and playing when they shouldn't or random people walking around the players area eyeing up your guns, then by all means complain away. Anyone with any common sense can see that the players cards are a good idea.
Now if the promoters don't take advantage of the players cards, and use them to enforce the rules and security, well that's another issue, and one that Karlijn and Beard will undoubtdly be working hard to resolve.
