After creating an event in Lyyti and having sent QR codes to participants (either in their confirmation message, name badge, ticket or mobile ticket), you can read the code later on at the event venue with Lyyti's mobile application. It is free to use and can be found by searching "Lyyti" in the App Store.

The application needs internet connection to download participant data from Lyyti into your mobile device. In addition, you need a Lyyti username (e-mail address and password) and at least viewing rights to the Lyyti event to which you are about to read QR codes.

Can I read QR codes with several devices?

You can read QR codes with several devices as long as the event's viewing or editing rights have been shared to another Lyyti user or e-mail address (see sharing instructions). Viewing rights are enough to allow reading QR codes, so you don't have to share modifying rights, if you don't want to. Sharing viewing rights is free of charge.

Basic functions

Open the mobile application and login with your Lyyti username (e-mail address and password). You will now see all your active events.

1. Search events
   • The search remembers your last searches.
   • Click on the event's name to open the participant list.
2. Events are divided in three tabs: favourites, active and past events
3. If a colleague has shared an event with you, there's a Shared tag after the event name.
4. Event/participant list.
5. QR code reader.
6. Profile.
   • Settings
     • Language: You can use the application in Finnish, Swedish, English, German and French.
     • Restore default settings (restores participant status selections and clears search history).

Showing participant details when reading QR codes

When reading QR codes, Lyyti shows you the following participant details by default:

• information about QR codes validity
• participant's name, last name and e-mail

For each event, you can select what details you want to see on check-in. Select an event from the list and go to Check-in settings.

At the end of the page, you'll see a list of participant details that are shown always when reading QR codes.

1. If you also want to see participant details when checking in participants by hand (swiping participants from the participant list), select Show participant details: Show when check-in is done manually.
2. Choose more details to be shown by tapping on Add details.
   • Choose the questions/details you wish to add and then tap Add details at the end of the list.
3. To hide details, tap on the details and select Hide details.

Read QR codes

Lyyti's QR code reader reads codes automatically from all your Lyyti events. To start reading QR codes, click the QR reader.

Next, show the code to the reader. You will get a notification:

• If the code is valid: 
  • You'll see the a green arrow as a sign that the code is valid and the participant is now marked as Attending. The participant details shown here depends on the settings selected in Check-in settings (see above).
  • You'll hear two high-pitch beeps as a sign of a valid code and successful check-in.
• If the code is not valid: 
  • You'll see a red error message.
  • You'll hear a descending beep as a sign of invalid code and unsuccessful check-in.
    
    Possible reasons for invalid codes:
  • The code has already been used (each code is single-use only).
  • The code belongs to an event you don't have rights to.
  • The code is not from any Lyyti event.
  • The code is unclear or blurry (if printed etc.)

Go back to the event list by closing the QR reader from the top left corner.
