Tickera is a new WordPress based event ticketing system that features QR Codes, works with PayPal or 2Checkout payment systems. You can easily sell tickets for your event on your website. Tickets with the individualized QR Code are delivered via email.
At the event, rather than taking up tickets or checking attendees names on a list, just scan the QR Codes with the free Tickera iPhone app!
Install the WordPress plugin, download the iPhone app and your on your way. There is even a WordPress theme called Themetick which comes with the starter version of Tickera installed!
The best part: QR Codes tickets can be presented at the door on smart phones without needing to print them out!
