Automated teller machine with an encrypting card reader and an encrypting pin pad
View Patent ↗A banking system operates responsive to data read from data bearing records. The system includes an automated banking machine comprising a card reader. The card reader includes a movable read head that can read card data along a magnetic stripe of a card that was inserted long-edge first. The card reader includes a card entry gate. The gate is opened for a card that is determined to be properly oriented for data reading. The card reader can encrypt card data, including account data. The machine also includes a PIN keypad. The card reader can send encrypted card data to the keypad. The keypad can decipher the encrypted card data. The keypad can encrypt both deciphered card data and a received user PIN. The card data and the PIN are usable by the machine to authorize a user to carry out a financial transfer involving the account.
