What is the best way to track individual worship attendance using a Connection Card

Here are the steps to do this.

1. Create a group for each of your services including online ones.
2. In step 1 be sure to check the radial that this group is for "Adult Worship / Youth Attendance."
3. In step 3 be sure to answer the profile questions the same way for ease of reporting.
4. Create a "Connection Card" group.  
5. To the form fields on the bottom of the registration settings page, add a "Service I'm attending" custom registration field.  Be sure to set up each response to auto-register to the correct group.
6. Add the keyword you want people to text to get the link to register.

Now, all you have to do is create the communication content: a slide for the screen, an ad for your bulletin, and script for an announcement.  If you want to use a QR code you can do that too.

You won't get everyone to register.  So, be sure to count the number of people in a service.  Then even up the total attendance for the service by adding the difference between individual attendance and actual attendance in the "# of Visitors/Guests" field.

This will give you the data to run any attendance reports you need.  The actual meetings page will give you a quick overview as well.  Notes from the report are available here as well.
