I wonder how many 49ers fans are aware that they may soon be guinea pigs for some invasive screening. I have no idea what this technology is, aside from a brief explanation from USA Today:
Radiation and chemical sensors survey the passers-by for explosives, X-ray machines scan for weapons, and a color-coded light array gently guides users through the process with green, red and purple prompts.It is supposed to passively search large crowds so that there are minimal bottlenecks (since private companies are quite interested in not irritating their customers). But, will there be some sort of notification in the fine print on tickets?
(I also find it interesting that the article notes that Disneyland Paris tried this technology.)
