A method, system, and apparatus for capturing information is disclosed. The method includes emitting energy of a first wavelength from a first energy source located proximate to a first end of a digital pen and forming a first set handwritten markings on the substrate by causing the substrate to image as a result of an exposure of the substrate to the energy emitted from the first energy source. The method also includes detecting by an image-capturing sensor of the digital pen a first detected portion of a position-identifying pattern on the substrate and storing in the memory a digital document file comprising the first set of handwritten markings and the first detected portion of the position-identifying data. An apparatus and system for performing the method is also disclosed.
