I've done a similar app, but it keeps a gui up awaiting a timeclock punch.
You need to tackle this in phases:
1. what os and get the gui to start at bootup.
2. start a separate thread that reads/blocks on the coin.

you need more specific questions to get better help

Subject: Coin-operated kiosk written in python -- need some help...

I posted a few days back and didnt get much of a response, so I figured I
would post again
with more detail. I am running gnome under fedora core 4.

I want a kid to be able to drop a quarter into a coin slot and get 15
minutes of time on
an account that has "restricted" Internet access via the firefox web
browser.  We are
experimenting with different ways to allow kids to safely surf the web
during school hours
while recovering some of the cost for bandwidth.  I have written a python
program that
detects the coin drop and adds 15 minutes to a gui written in tkinter. The
gui contains 2
buttons and the usage time.  I need a way for my gui to display from machine
bootup until
shutdown and through multiple logins and logouts of the web browsing
account.  I am
familiar with kiosk setups but I dont know how to code my python program to
display its
gui at the login screen and continue running through multiple sessions of
users logging
into and out of the internet acct.

I thought making my kiosk program a daemon would work, but I cant get the
gui to display
at the login screen and then there is the problem of having the press of a
button on my
gui enter username and password information.

Basically, I envision the following sequence of events...
1) Machine is turned on and boots up
2) My kiosk is started (maybe as a daemon)
3) The daemon uses Tkinter to display its gui with the buttons and time
4) User drops coins and time on gui is incremented
5) User presses the start button
6) My program logs the user into the Internet account
7) Secure firefox is started
8) My program starts counting down the time on the gui
9) When the time reaches 0, the user is logged out
    When the user presses stop on my gui, they are logged out
     The user can drop more coins at any time during the session to prolong
the session
10) Timer resets to 0 awaiting the next customer to drop coins

Any help on how to display my gui and log into an account using python would
be much
Cheers -Jon
