How does the technology work?

The technology behind our talking books, cards, and puzzles – simple for children, but carefully developed behind the scenes.

How Readioo works

The technology behind

The magic of Readioo is not just the reading pen – but the interaction between technology and printed materials.

When the child taps on an image, a word, or a puzzle piece, the pen reads small optical codes embedded in the print.

The pen recognizes exactly which audio point the child has selected and plays the correct narration, word, music, or sound effect.

For the child, it feels simple: tap and listen. Behind the scenes, it's a combination of special printing, optical technology, audio production, and careful testing.

At Readioo, we make advanced technology simple – smart hardware that children can use completely by themselves.

What's inside the reading pen?

Readioo's reading pen includes, among other things:

  1. an optical sensor that reads the codes in the print
  2. a chip that interprets which sound point has been activated
  3. memory where the audio files are stored
  4. a speaker that plays the sound
  5. a battery and charging port
  6. software that links each code to the correct sound

This means that the sounds can be played directly from the pen, without the child needing to use a tablet, mobile, or the internet.

Why is special printing needed?

Our products are printed using standard ink colours. At the same time, the optical code layer must be precise and legible enough for the pen's sensor.

This means that the print file is not just about how the product looks to the eye, but also about how it can be technically read by the pen. Colour, contrast, code placement, and print quality all need to work together.

The goal is for the child to see a beautiful book, a fun card, or a puzzle – while the pen sees the technical information behind it.
