You can redeem your voucher here. You can redeem your voucher for a free Print@home ticket on our ticket ordering portal. Online vouchers can only be redeemed for a Print@home ticket online and you will need to enter the 23-digit online voucher number. Vouchers cannot be redeemed or exchanged at the venue. The Print@home ticket is free to you as an invited visitor, as the costs of the ticket will be borne by the exhibitor from whom you received the invitation. Since the exhibitor will be charged only if you actually attend the trade fair and pass through the turnstile, you do not need to inform the ticket service or cancel your ticket if you do not use it.
