You could read a slightly more technical description of the systems at:
Transponders http://www.amb-it.com/
Camera http://www.finishlynx.com/
OBRA currently has a 35mm slit lens photofinish camera (uses film as opposed
to video). Unfortunately the operation of this camera is so cumbersome that
it is rarely used. We will be using it next weekend at the Alpenrose
Challenge so if you are interested come on out. You should come out to the
Challenge anyhow because it will be world class tack racing and you don't
get to see that all that often. I am trying to convince everybody that OBRA
needs to get a FinishLynx or other line scanner video finish line system but
the $12,000 cost, last time I checked, is putting people off a bit.
The transponders are another issue that has been discussed here before.
Thee is a company that will rent and operate that system here but the cost
is higher than most people are willing to pay. I am watching the
development and costs of commercials systems and another member is working
on a custom built system using off the shelf RFID chips. It may be a while
before we start seeing these used frequently at local events.

I was curious about the the yellow transponders on the left chainstays of
all the Tour riders bikes. I found a good description of the system, and the
finish line cameras at:
