SD•X is a revolutionary interactive information technology developed by SD•X Interactive for business, education, and entertainment. With the touch of the "pen," SD•X makes virtually any printed media come alive — playing back essentially unlimited audio content.

The SD•X pen and enabled print generate a totally unique experience. After SD•X assigns nearly invisible codes to printed areas, the SD•X pen recognizes these codes and triggers specific and unique responses, such as voice in multiple languages, music and sound effects, questions and answers — anything recorded can be enabled on printed media!
