Yoto cards are special cards used with the Yoto player, a device designed for children to listen to stories, music, and educational content. Each Yoto card has a unique code or design. When you insert a card into the Yoto player, it plays the audio associated with that card. This makes it easy for kids to choose what they want to listen to by simply picking and inserting different cards. Yoto cards are fun, interactive, and help kids enjoy a variety of audio experiences without needing a screen.
