Digital pens are starting to take off in the U.K. public sector. The pens digitally capture information written on specially printed paper that features a dot pattern. A tiny camera determines the pen's location on a page and can store up to 40 pages of text.
Greenwich social workers say the pens fit in with their normal working patterns and don't create a barrier in the way laptops do.
This style of pen is being used by road test examiners before a larger-scale trial next year.
