Yahoo has rolled out new "Contact Cards" in Yahoo Mail that linger over a person's name in a message and show useful information about the person like their phone number, links to social profiles, company and title.
According to TechCrunch, Yahoo said that the new system is powered by Xobni technology.
Yahoo acquired Xobni in 2013 which was among the first companies to develop an email add-on, pulling in additional information about your contacts right into your inbox.
The Contact Cards will display the usual information like phone, title, email and more, along with a photo or a logo, if it's a company and links to social profiles, including Facebook as well as Yahoo-owned Flickr.
