The Anoto Live SDK can be used to develop a pen management application for digital pens from Anoto. Pen stroke data can be retrieved from the pen. Pen properties can be accessed and set in the pen. The application has full control of the transactions - it can send ink data (containing stroke data and pen id) to the back end and choose when to remove data from the pen (i.e. upon confirmation from the backend system). The current Anoto Live SDK supports the new Live Pen™ 2 and Live Pen™ 1 (DP-201).
