The apparatus is controlled by a credit card following customer identification, and comprises a series of peripheral units operable by a central unit 10 in accordance with a determined program. The apparatus is normally supplied by mains voltage, and comprises a relay device 34 sensitive to voltage drop in order to connect the apparatus to an electric battery 36. A counter 48 arranged to decode the stage of the program under execution induces an emergency cycle controlled by a timer 44, of which the times coinciding with said stage selectively operate the peripheral units, in order to perform the essential functions for closing the interrupted transaction in a defined manner which is intelligible to the central unit.
