Hi Grant :-)
I took a look (Firefox 1.x, Windows PC). Since I`m not in the after market and have no clue what HID means, I had no real interest in the site.
On a generic level, though, I suspect that the small white font on the black background is going to be hard on anyone`s eyes.
If you subscribe to the view that a Web page should be mostly scannable, in that most people only scan through a page in 4 seconds, this page isn`t scannable. So I would assume you don`t subscribe to that view. There are quite a number of learned articles demonstrating this principle, but perhaps in the HID field it`s not true.
Overall the page looks quite nice. I like the black background and gold lettering. It looks cool, high-tech, and professional. What I`d probably do is set the text areas to a much lighter background and use black typeface. You could use table cell background images to have a sort of textured "paper" look for the cells, then put your content over that.
Beyond that, I can`t say much as I don`t understand the product.
Thanks for the input, but i don`t under stand what you mean by if the page is scannable? can you explain it little more?
