Smart cards can hold up to 32KB of data and have encryption capabilities. They provide security for banking, mobile payments, and ID verification. Smart cards use microprocessors and memory to store and process encrypted data for transactions and access control through card readers. They provide flexibility, security, portability and increasing storage capacity compared to magnetic stripe cards.
