Would like to check-in event participants using a QR code that will also update the attendance status of the participant. Is there an extension available for this feature? Any help is appreciated...thanks

We have built such a solution, though no extension is available.

The key is that the QR Code simply needs to contain a URL request, with embedded querystring parameters such as event_id and participant_id. Pretty much any stock QR scanning app will recognize it as a URL, and will simply pass it on to the device's browser.

We wrote a simple PHP program that was called in the URL, that grabbed the querystring parameters (event_id and contact_id in our case), and called the CiviCRM API to change the participant status to 'Attended'.

Our app also returned a screen back to the device browser that reflected add-ons that the participant had purchased (lunches in our case).

This does have a bit of a security risk. We got around this risk, by having a separate URL the device browser would be directed to that the user could log into and have a cookie dropped onto their device (which was then subsequently interrogated by the main PHP script to validate).

We created an event app for one of our clients which enables the participant status to be updated via a QR code. More info here: https://vedaconsulting.co.uk/event-manager-app

  • Hi Daniella, thanks for your response, that actually helps. The issue here is, we dont have an app yet. I need to generate a QR code for my participants and scan the same using any scanning app that will update my CiviCRM database. I can generate a QR code, but I am not sure how to update my CiviCRM DB after the scanning is done.

I don't think it exists already but I do know Circle Interactive have worked with barcodes and QR codes in a few previous projects: - https://civicrm.org/blog/andyw/bitcoin-payment-processing-with-bitpay

  • Hi Jon, thanks for your response, but that's got to do with enabling bit coin's with CiviCRM...may be it will be of use to me sometime down the line :)
