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.

Plusdial platform has been under constant evolution all the time, and we’ll soon publish our Open API specifications, as a means to modernize ticket purchase and payment to meet growing desire for open data and interfaces and integrated modular services. That is; Plusdial ticketing system has developed more and more into an integration platform for any payment and order & delivery channels. This means that we can provide a uniform set of tools for end customer services, ticket inspectors, reporting, user management etc. while traffic companies can basically – without tenders – publicly invite all relevant payment companies and application producers to come on the market on their own risk: PTC sets the key criteria on security and ticket outlook, and Plusdial provides connecting APIs. PTCs agree on commercial terms with the suppliers. All mobile tickets, whether delivered via SMS, an app, or even web site or such, have uniform security elements for inspection; Plusdial also provides on-line tools for inspectors; we can – if so needed, create the tickets in also in bar code or QR code form. Any payment provider interested in offering payment services, may – should PTC evaluate their revenue share or other compensation schemes tempting enough – offer their solution as payment means for tickets, without PTC having to force ticketing customers to be users of one selected provider, and application companies are equally able to enter the market to compete over customers’ favour. The customers then decide which way or ordering and payment is the best!
