[Klug-general] Indentifing Local machines on website

[Dan Attwood]

I've got 3 student information terminals. They are in one pcs that have
card scanner attached to them and run windows.
They run chrome which has a website. When a student scans their card some
jquery passes of to php via ajax shows them their print, timetables etc.
What i'd like to be able to is to log which terminals have been scanned
though.

I've tried to do this by calling a local file on each terminal but chrome
blocks calling files from the c:\ drive.
I could use a different url for each terminal, '?terminal=number1' etc, but
this would policies to ensure each terminal called the right url and also
the page has a refresh built in and I'm concerned that this might cause an
issue.

Can anyone think of better for this?
