HP and Nokia developed digital pen

HP and Nokia teamed up to add more mobility to a system that was designed to quickly and efficiently transfer information from paper forms to databases, according to Eric Chaniot, vice president and general manager of HP's digital pen and paper business. HP's current digital pen uses a cradle wired to a PC via USB. Users have to put the pen in the cradle in order to upload data.

The key markets for digital forms are health care, manufacturing, financial services and government, where transferring information from paper forms to computers typically costs about $1 per page and causes delays in work processes, Chaniot said. Digital pen technology takes that cost down to about 25 cents per page, according to HP.
