A prototype is the first or original example of something that has been or will be copied or developed. It is a model or preliminary version. Virtually all innovative designs emerge in the interplay between two dueling representations: the wish list of specifications that describe and define the new ideas, and the prototypes that attempt to embody them.


While traditional methods of prototyping take a long time to make, a low fidelity prototype takes a lesser time comparatively. It is easy to evaluate and iterate the design. Moreover, the prototype is easy to understand and can be modified to meet user requirements without much expenditure.
A low fidelity prototype of the design that has been suggested is shown in the next page. The design primarily has an interface which is secure, as it can be used only by authorized users having unique ID and a password. Lecturers and the administrator can be provided with such log-in IDs and passwords while course leaders do not require it. Basically, each student will be registered once while entering the university at the main entrance by fingerprint scanning. This is done so that only authorized people enter the university. There will be a second time of registering the students when they enter their respective classes. This can be done using the code checker on the student's ID card with OCR or Optical Character Recognition. When this is done, the attendance is automatically registered into the attendance manager system shown below.
When the lecturer for the p ...
