    The machine is connected to the database of the bank. The electronic signature on the card contains all the information about card. When the merchant swipes the card on the card reader the bank validates it.

    The card info. Usually goes to a payment gateway processor. The processor checks to see if the card is valid, if it is approved the funds for payments are held in the cardholder's account.
