RabidRabbit23 (1576305) writes "I volunteer for a non-profit that organizes Model UN conferences for high school students. We need a quick and low cost way to record votes done by the students in large committees. There will be two or three committees with about 200 students in each. We need to be able to record yes, no or abstention vote and must be able to identify each student's vote. We looked into radio response clickers but it is very expensive to buy 400-600 clickers. They cost about $40 at university bookstores, which is way out of our budget, but we don't know what kind of discount we could get by buying directly from the manufacturer. We do have wireless internet but we do not have enough bandwidth to support everyone using a laptop. Does the Slashdot community have any suggestions for a better way to record the students' votes?"
