I want to congratulate you for your softwares. Before investing I must be sure of one thing:
During the validation (and verification) tickets before a show for example, I do not have internet connection. So, is it possible to use your ticket validation program without Internet connection (ie local)?
If so, how?
Thank you for your reply.

HI Burno,

How are you today?

The mobile apps are designed to connect to the Event Espresso database (which is your website). The mobile app checks to see if the ticket is valid, or not already been used. So, like most ticketing platforms the device will need to be connected to a communications network of some kind so it can validate the tickets.

If you really need this feature we might consider adding it if you can help with the cost (more information about Sponsored Development sponsored development), otherwise we’ll add it to our list of feature requests. The challenge I see with making our app store the registration information locally that if you want to use two mobile devices and make sure that a ticket is not scanned by one device in one location and then reused again at another device in another location. The two mobile apps would have to communicate somehow and sync the data between the devices. Again, that would take a communication channel somehow, whether wifi or bluetooth technology.

Does that all make sense? Can you tell me more about your situation so I can understand what you need a little better?

Hello, thank you for your reply.

Actually I have a system with a USB bar-code reader. The database is in my computer and  when I scan the ticket, a app see if the ticket is valid. But I don’t like the system bar-code.

My idea is :

– the database is in my computer (a save of the database wich is in the website)

– the mobile phone and your app communicate by Wifi or Bluetooth with the computer and validate the ticket

Is it possible?

Hi Bruno,

This is not possible since our apps are designed to communicate over the web with a server running Event Espresso, and it uses its own qr code system for scanning tickets.

Would it be possible to do local validation by hand, by getting the number from the ticket and comparing it to a spreadsheet, or alternately, to run a backup copy of the entire site locally and do validation against that?

Hi Josh,

You could export a spreadsheet of the attendee list and use it to check against the tickets.

With your other idea, I think it might work if you can clone the site onto a local server like MAMP, then set up a local wifi network. The scanning devices would use an endpoint based on the network address, which would likely involve changing the local WordPress site’s Site URL and Blog URL settings to use the network address instead of localhost. I haven’t tested this out in some time, but I used to test the ticketing app on a localhost this way.

One issue that you might run into is the local site’s database and the one on the live website would be get out of sync after the event.

Hi Josh,

Yes, you can print out the registration records and do it manually.

The mobile apps need an internet connection so if you don’t have that then they won’t work. You could copy your entire Event Espresso DB to a local computer and run Event Espresso locally, but still the apps won’t work.

Does that help?

Thanks to both of you; both answers cover all the bases and allow me to find the right solution for the client.
