Despite the growing use of technology in various areas, there are still some processes that are not computerized and depend entirely on the use of paper and pen. A good example of this situation in our country is the vaccination card.In many health units, the process of recording vaccinations is done using paper forms filled in by hand. This process can lead to inconsistencies and loss of information, which can hinder vaccination coverage in the municipality, vaccine losses and difficulties in obtaining information.With the end user in mind, vaccination records in Brazil are kept on various paper vaccination cards, which are easily damaged and lost. Vaccination is one of the most important and effective ways to prevent many diseases, but it requires centralized records to prevent damage and easy access to be able to check and keep track of the proper vaccine doses you will receive throughout your life.
