hello
i am in saudi arabia
and i want to get vending gum machine from usa
but the problem the people here not use coin 
are the vending  machine accept note (paper currency)

Gum costs considerable less than $1.00 US, so it would be difficult to
find a gum machine that takes paper money. WHat I would do is to look
for a way to convert the coin-acceptor to one that takes the money
your country uses.

Go to your local version of the "Yellow Pages" and go to the
classification for "Vending Equipment" --call a couple companies there
and discuss the options with them.
