A modern approach was adopted to overcome the disadvantages of the conventional system. In this approach, the OCR and machine learning model were used to produce accurate results. Supervised and unsupervised both learning model was incorporated to teach model.

This approach is much more reliable than conventional. But this approach requires a lot of data, high-quality trainer and much more trained professional to build an efficient model. This hard word is just required one time, the result is fantastic.
