All in One Card: A Knowledgeable Tool

Abstract

Almost a decade ago, we could all have heard of the smart card and its role in the financial sector, especially for retail transactions. The smart card provides special security compared to normal monetary transactions. But its implementation in the case of retail payments has not been as popular. But it was really useful in the area of transit payments and personal identification. But some other sectors, such as mobile telecommunications, found this more useful and began using them in mobile phones as subscriber identification modules (SIMs). But in today's world, people need to carry different cards like PAN cards, driver's licenses, Aadhaar cards, etc., which makes people more uncomfortable as they have to carry different cards at the same time.
