You can set multiple locales via your admin, so that customers at the machine have a choice of display languages.
To do so, first ensure that your machine and server are on v7.1 or higher.
Within your admin's 'Machine Settings > Setup' panel, add the desired default locale first, then add additional language options (up to four total.)
For instance, if your machine is located in Newfoundland, you may wish to select: en-CA, fr-QC, ga-IE.
The choices for other machines will override the 'Global' setting, which is the default for all paired machines unless otherwise defined.
'Change language' screen
After enabling multiple languages, you'll notice a 'Change Language' link on the upper-right corner of the machine screen.
Pressing this button will give the user a choice in the UI language for the rest of their interaction with the machine.
Translating additional languages
If your desired language(s) are not yet fully translated, we'd more than welcome contributions to our open-source translation project.
Please contact support to indicate which languages you'd like to contribute to and we'll send you a link. For a native speaker, it should take about 30-40 minutes to complete.
