Blockchain technology is becoming more and more popular day-by-day with an escalating interest in numerous applications ranging from data management, financial services, cyber security, Internet of things (IoT) and food science to healthcare industry and brain research. There has been a remarkable interest witnessed in utilizing applications of blockchain for the delivery of safe and secure National Identity (ID) management. Also, blockchain can reform the traditional ID management practices to a more reliable means in terms of effective use and distribution through safe and secure data sharing. In the future blockchain could be a technology that may potentially help in personalized, authentic, and secure ID management by merging the entire real-time user data of a citizen and presenting it in an up-to-date secure setup. In this paper we review both the existing and latest developments in the field of ID card system by implementing blockchain as a model. We also discuss the applications of blockchain along with the challenges faced and future perspectives.
