There is no need for a 'ticket' to be sent to a customer, as it is the travel voucher that acts as the customer's ticket.It is essential that your customer prints out and presents the voucher when that is a requirement, otherwise they may show an electronic copy on a mobile device. The voucher is unique to each booking and acts as proof of purchase. Customers simply present each travel voucher upon commencement of the travel service, together with valid photo ID for purchase verification.
