The United Nations Children’s Fund quickly initiated a mobile program to raise funds to help the survivors of the recent devastating earthquake in Nepal, and while text-to-give is still playing an important role for the nonprofit, its strategy is evolving with a bigger focus on social commerce, including $Cashtags from Square. Square introduced $Cashtags last month, enabling anyone to create a personalized name, such as $Unicef, to get paid through Square’s online payments. Including the $unicef tag in social media posts enables mobile users to quickly make a donation.
