If you use a voucher, you accept that the data that you specify in the registration process will be given to the exhibitor who invites you to a free visit. This can be used by NürnbergMesse GmbH for charging the exhibitor for the tickets, for checking the vouchers exchanged and for contact between the exhibitors and their visitors e.g. for advertising purposes. If you do not agree, you can, of course, buy a ticket at the registration counter on site without providing this data.
