The invention relates to a device (10) for reading magnetic stripe and/or chip cards, in particular bank cards, EC cards and/or credit cards. The device (10) comprises a display unit (14) and a touch module (16) arranged in front of this display unit for determining a position of a touch of a display area. Further, the device (10) has a security module (18) for controlling the display unit (14) and the touch module (16). The security module (18) transmits first data for displaying a keypad for entry of a PIN to the display unit (14). In response to a touch of the display area, the touch module (16) generates second data with information about the position of the touch, encrypts these data and transmits the encrypted data to the security module (18).
