Question:
How If I use a debit card in across the country from my bank, how does the transaction get to my bank?



Replies:
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.
