Patient registration is a service that every medical institution has to provide, and is also the first point of contact on many occasions. With all the changes in the healthcare environment that have occurred, hospitals have been moved to adopt the business approach of customer-oriented service to increase competitiveness in order to survive in the long-term. This approach emphasizes multiple options for registration, increasing the convenience to the customer. Improving the quality of registration is the goal of every medical institution.

The system provides a personalized approach and offers customers a further way of completing registration formalities. The registration system was assessed before and after the introduction of this automated system. Our experiences are detailed here to give others in this field the benefit of this particular example.
