Streamline Event Check-in with QR Codes and Rock Website or App

Overview

Problem

Trying to check-in 200+ people into an event in a timely manner can be difficult if you want to verify who has checked-in and who hasn’t.

Solution

Using QR codes sent to the participant and workflows that check the registration lets you control who has come and who has yet to come. The system sends a single QR code to the Registrar, which can be shared amongst the registrants. There is also a way to search for people who either didn’t get a qr code or lost it.

Details

There are 2 methods to verify Event Registrations using QR codes, via web or via app. Both work well, but the app offers an easier interface for the person doing the check-in.

The Backend

Registration

When Creating your Registration Form, you need to add a field with the Key "CheckinDateTime" that is of type "Date Time". This is the attribute that will be used to store the check-in date and time. Make it an "Internal" field.

Workflow

The workflow handles everything for the web version of check-in and the final steps for the app version. It verifies which registrants are being checked-in and sets the check-in Date attribute required on the Registration Instance.

Workflows do not allow you to populate single-selects or multi-select fields on the fly after the workflow has been loaded. You also are not able to do it from Attributes that may already be loaded into the workflow. Our workaround is to reiterate the workflow with new page parameters and have the workflow move through different activities based on those parameters.

This workflow uses an Action "For Each" which can be found in Blue Box Moon's Workflow Stimpack. You can download it from the Rock Shop at PackageId=68.

Things to modify within the workflow:

"Registrar or Registrant" Attribute
Inside the Values field is a "LEFT JOIN PhoneNumber pn on pn.PersonId = p.Id and pn.NumberTypeValueId = 12" (replace 12 with your mobile phone NumberTypeValueId)
Redirect Action (x2):
This is the page that you use for WorkflowEntry. Substitute "form/371/" with your own workflow entry page and this workflowtypeid.

QR Code

The QR Code presents a URL pointing to the workflow for the web version and a deep link to an app page for the app version. It contains 2 parameters, the Registration Instance Id and the Person Alias Guid

Lava Shortcodes

Registration Check-in Chart
This shortcode is used to display a chart of the number of people checked-in vs the number of people who have not checked-in. It is used on the Registration Instance Detail page.

The Frontend

Website Pages

The url from the QR code should point to a Workflow Entry page, or a deep link with a fallback to your Workflow Entry page you use for your public forms for example we use /form/371 to point to the correct workflow, then the url has the appropriate parameters ?RegistrationInstanceId= and &Person=

Mobie App Pages

Because the mobile app doesn’t allow for redirecting back to your workflow Entry Page like we can on the website, we need to create more pages to handle the check-in

People Search for Registration Check-in
Allows you to search for registrants/registrars tied to the registration instance. This block does not allow for PageParameters, so you must hardcode the Registration Instance Id for every Event.
NOTE: You must hardcode the Registration Instance Id of the event into this block. At this time the Search Block does not read the PageParameter.
