# Attendee Check-in & QR Codes

## App Prerequisite

To use the QR code scan feature, the Mobile Check-in app must be updated to Version 1.0.10 or higher.

## Check-in Options

### QR Code

To check in an Attendee using the QR code scan feature press the **capture a QR code** button on the home screen and scan the QR code. A valid QR code will start the check-in process and provide the user with relevant details about the Event.

If you are using an iOS device and need to close the QR code scanning feature without scanning a QR code, click the **Cancel** button.

### Attendee Name

There is a refresh button on the top right for manually refreshing the list in case there are data changes from Salesforce. Also, the sub-header displays the total checked-in Attendee count as well as total registered Attendee count.
