When a customer orders a ticket - by simply sending an ordering SMS message - it is transmitted to the telecom network’s SMS Centre, which delivers it using protected Internet or VPN connection to Plusdial's Router server. The Router forwards the order to the Ticket generator component, which first makes a billing request to the teleoperator’s billing system, and, after receiving an invoicing approval, generates the ticket, which is delivered through the Router to the SMS Centre and further to the customer.
Ticket revenue collected by teleoperator will be paid directly to the Public Transport organization monthly according to the terms of their mutual contract. With Plusdial's on-line reporting tool the Public Transport organization can verify that telecom operators' reports and sales figures are correct.
The customer service, which can also act as the back-up help desk for ticket inspectors, have also an on-line access to the ticketing system's database. If a customer calls to the customer service, any events can be searched based on customer's mobile phone number.
Inspectors can rely on help desk's support in determining ticket validity in cases when customers say they don’t find the ticket message, their phone is out of order or battery is flat, etc. System also supports making validity queries by e.g. SMS. In most cases, though, the validity of a mobile ticket can be controlled visually by reading the security control code or automatically by using handheld validators or the fixed units mounted on the vehicles or at stations.
