The Grenadine check-in app is used by organizers to check people into events and sessions. It helps you see if people are properly registered/signed up for the things that they want to attend.

The Grenadine check-in app

You can use the Grenadine event check-in app to check people into your event or into a session.

How it works

The check-in app is a native iPhone or Android app that can be easily downloaded from the App Store or Google Play. To use the app, you log in using an organizer credential. Typically, this will be the same username and password used for logging into Grenadine Event Manager.

Once logged in, choose the action that you want to carry out (check-in into event or check-in into a session) and start scanning tickets or badges QR codes.

If you’re scanning without a Wi-Fi connection, the check-ins are queued up on your phone, you will then have to manually sync your device with our servers by clicking on any refresh icon in the app. If you have an active Wi-Fi connection, this should not be an issue, your scans should be immediately synced with our servers. If for some reason your app is not able to communicate with our servers, you can export the scan data manually by going to the “More” menu, clicking on “Local scan data”, clicking on the share icon in the top right corner and sending us the generated text at support@grenadine.co.

You shouldn’t experience camera freezes, but if it does happen, please click on the “More” menu and go back to “Scan”. This will reset the camera.

Scan behaviors

You can change the behavior of the app when it is scanning a QR code. We offer three behaviors discussed below. To change the scan behavior, click on the shield icon in the top right corner when you are in the scanning view.

Loose scan behavior

Allow all the QR codes without validating the admissibility of the person on the server.

Recommended if you have no (or a slow) internet connection.

Strict user driven behavior

Validate the admissibility of the person on the server. If the person is not allowed, the user will be told why and will be asked to device if he lets the person in.

Recommended if you have an internet connection.

Strict system driven

Validate the admissibility of the person on the server. The system decides if the person is to be let in.

Recommended if you have an internet connection and the user doesn’t have time to make decisions.

Letting other staff members use this app

If you want to let other staff members use this app, without sharing your personal login information, you can create login credentials for whoever requires them. Simply go to Global settings -> Users and add as many users as needed to the checkin role.

Tips and tricks

Below are a few tips and tricks to help you if you have issues scanning tickets quickly. Even though we use state-of-the-art algorithms to read QR codes efficiently, light conditions and aged hardware can slow things down.

Increase intensity of the phones’ backlight

If you’re scanning a QR code on an attendee’s phone, ask them to increase the intensity of their phone’s backlight.

Use a lamp

In low light conditions, use an external light source to light the QR code. The scanner works better, and is quicker, when there is a sufficient amount of light.

Lay the ticket down on a table

Doing so will reduce the amount of shaking and the scanner will be able to pick up a decent image of the QR code quicker.

Favor newer devices

Newer devices usually have better cameras and therefore scanning QR codes will be much faster.

Self check-in (only for iPad)

The self check-in mode is useful if you want to let your attendees check themselves in your event or a session.

You should only use the “Self check-in” mode with an iPad. This mode is only available on iOS. You can enable this mode by going to the “More” menu, clicking on “Self check-in” and entering the pin “0000” without the quotation marks.

In the “Self check-in” mode, the name of the event is displayed at the top. If you are scanning into a session, the title and the start time of the session is also displayed.

The admissibility validation discussed above is never used in the “Self check-in” mode, everybody is let through.

Same as the regular check-in mode, the scans are synced immediately, but if there is no WiFi, the scans can be sent to the server at a later time.

In this mode, you will probably want to use the front camera. You can switch which camera is used (front or back) by tapping the screen multiple times, entering the pin and choosing the option “Flip camera”.

You can leave this mode by tapping the screen multiple times, entering the pin, and choosing the option “Leave mode.”

To switch which session you are scanning into in this mode, you need to leave the mode, click “Start”, click “A session”, selecting a different session and re-enable the self check-in mode.
