Read pen has two main parts:
1. Read pen Camera: for scan out the special voice code printed in
book, it like Scan camera which use in super market checkout desk,
but this camera is more smart and accurate to recognize adelomorphic
code printed on book.

2. Read pen Voice player parts: this parts similar like normal mp3
Quran pen player, build in famous reciter's voice,
and with Quran read pen system software to control scan and voice
play.

While use pen to touch the specially printed book pages, the camera of
read pen will scan and recognize the voice code then software will
search in data back and find out which voice data is match this code
and play it out.
