TableCheck supports 18 languages and it is possible to enable as many of them as needed. When a language is enabled, the entire content of the TableCheck page can be localized to the enabled languages.
In order to enable an additional language (apart from the default), go to Shop Settings on your settings page.
Note: If you don't see Shops option on the left, go to Setup and click Settings in the drop-down list.
Click the Setup icon once you are on the Shops page
Select the languages you want to enable under the Online tab & click Update Shop.
Now go back to Online tab, all the fields where localization can be done will have a "+" icon against them.
Eg: Message from Merchant
Click the "+" button, an additional field will appear where another language translation can be added (Thai in this case)
Note: You can click the "globe" icon to enter auto-translation, however since it would be Google translation it might not be 100% correct. Hence it is always recommended to either translate manually or validate the Google translated content.
Update the Shop once the Thai content is added.
Now when a diner selects Thai on the TableCheck page, Message from Merchant will be displayed in the Thai language.
