Moshtix Case Study

High Distinction assignment

By Annie Tran

MOSHTIX-How it applies to the real world

This website involves booking tickets for a variety of events in different states across Australia. Users can either purchase their moshcard at a Moshtix outlet and register their details on the site or they can purchase tickets online or through phone using a credit card. They can also register as a member without previously ordering any tickets.

On the website, events can be searched by date, venue, category (e.g. Live music, festivals) or by keyword.
