This module will automatically set the currency and language based on your customers location as soon as they visit your website.

For example, A customer visiting from the UK can be set to GBP currency and English language. Someone from Portugal can be set to Portuguese and EUR currency, while someone from Brazil can be set to Portuguese language and BRL currency.

Languages and currencies can only be selected for those which you have installed and configured. If there is no match then the default language and currency will be used.

It works by matching the customers IP address to a list of locations. An additional database table needs to be imported using a free IP to location database download. The database can be downloaded periodically from this page in the correct database format.
