Telecommunications......I would think that if your bank agrees to give a
debit card (cash station) then your balance, PIN, etc. is held in a central
computer.  When you got to get money, the cash machine goes to the central
computer, which access your account and says, yes/no he/she has the money,
and tells the cash machine to give you money.  Then it sends a transaction
to your bank, saying you withdrew so much money and debits your account.
