# How to check in

{% hint style="warning" %}
An internet connection is required to use the access application! If your mobile internet coverage is inadequate at your event, make sure you have a Wi-Fi connection to ensure smooth access.
{% endhint %}

### The check in process

1. Download the application to the phone you used to log in
2. Log in with your username and password
3. Hold your phone's camera over the ticket and read the QR code on it
4. If the QR code is unreadable or the scan fails, click the "Enter Code" button and enter the string below the QR code.
5. Check the result

### Possible results

The feedback always shows the type of ticket and, in the case of a registered ticket, the name of the ticket holder.

#### Successful entry

"Successful entry" message on green background: entry was successful, ticket validated. In the case of once-valid tickets, the ticket will no longer be usable. To avoid fast accidental scanning, a QR code cannot be re-scanned for 5 seconds after scanning. Another QR code can be scanned immediately during this time.

#### Check in failed

 "Login failed" message on red background: login failed.
