Apparatus for processing vouchers includes a drive system suitable for causing a magnetic track on a voucher to pass over a magnetic head (170) which is connected to circuits for controlling writing and including a data transfer unit (22) and a data modulator (23). The stepper motor (185) has at least five phases, and the same clock (21) is used to control the stepper motor (185), the transfer of data from said unit (22), and the data modulator (23) in order to establish control transitions which are applied to the magnetic head.
