Sweden’s blood service notifies donors via text message whenever their blood is used, The Independent reports. The initiative aims to raise awareness for the need for blood donation, which has recently been on the decline.
Donors are also able to share news of their contribution on social media channels.
“We get a lot of visibility in social media and traditional media thanks to the SMS,” Blom Wilberg said. “But above all we believe it makes our donors come back to us, and donate again.”
