Anoto Group (formerly C Technologies) is a cloud based software provider (SaaS). It primarily dispenses patented dot pattern technology which provides a methodology for accumulating digital big data from analogue inputs.

With around 45 employees, the company is headquartered in Stockholm and has offices in Seoul, London, Lisbon, Singapore and Boston.


Digital Pen
Anoto's main product is the Anoto Digital Pen, a combination of ordinary and a digital camera (and supporting hardware) that digitally records everything written with the pen. It works by recognizing a non-repeating dot pattern printed on the paper. The non-repeating nature of the pattern means that the pen is able to determine which page is being written on, and where on the page the pen is.

The dot pattern can be printed on a professional press or on a . Dots are printed in black; other colors of ink are invisible to the pen's sensor. On a color laser printer, CMY can be mixed to produce a near-black color that is . For offset printing, Anoto developed an ink color called "Anoto substitute black", a non--based black ink that is invisible in the IR region, allowing the user to include human-readable black marks with the dot pattern without interference.

While some of Anoto's licensees have targeted the consumer sector, with, for example, learning toys, most licensees sell their products to providers who put together customized systems. Anoto also sells a software development kit (SDK), numerous software applications, the Anoto Forms Solution (AFS). In addition, Anoto sells an ASIC design for the image processing component of the pen; most pen licensees use the same basic design of optical assembly and pen internals. Anoto has approximately 350 partners, primarily in Europe, the United States, and Japan.

Optical scan voting systems are based on Anoto technology.
