How do I convert a penID to a readable format?

Question

How can I convert the penID string to a readable format?

Answer

All pens with Anoto functionality have a unique ID; this is a 64-bit unsigned number called 'PenId'.

To make the penID easy to read and type, it can be converted to a 'character' format number with a checksum, called 'pen serial number'.
