Argentina, Belgium, Brazil, Chile, France, Germany, Mexico, South Korea, Spain, Sweden, the Netherlands, Vietnam are up for consideration to be added to the list of countries whose nationals can get a visa on arrival in India.

As of this year, India's visa on arrival program is available to nationals of Finland, Japan, Luxembourg, New Zealand and Singapore.

It seems to be not getting that much use currently. That's sort of a given when not-even 5% of visitors to India are nationals of the above 5 countries; when even only a bit more than 5% of such nationals are using it; and the program is so new in terms of its going live in India (and most visitors got their Indian visas because of the lack of clarity/confidence in terms of what would happen on arrival and when).
