AP-701 - What is a 'pen license' key?

Question
What is a 'pen license' key?

Answer
Anoto's new AP-701x pen models are the first pens Anoto have produced that includes a pen-specific license-key within the pen. The pen's license will only activate after you have performed a penDown on Anoto pattern for the 1st time. Once activated, the license will determine...

1. How long the pen can be used for before the license expires, at which point the pen will stop recording stroke data
2. On which Anoto pattern segments the pen will successfully record stroke data on

These pens are produced (and tested) in our factory and they are shipped out with their licenses deactivated.
