A smart card including a memory and a domain-specific language (DSL) interpreter is provided. The memory stores card data indicative of a real-time status of one or more attributes of the smart card. The smart card is linked to a service provider and card aggregator circuitry. The card data is stored in a format of the service provider and is updated each time a user of the smart card avails a service of the service provider using the smart card. Further, the DSL interpreter translates the card data to a format of the card aggregator circuitry based on a DSL script and provides the translated card data to the card aggregator circuitry. Based on the translated card data, the real-time status of the one or more attributes of the smart card is presented to the user by way of the card aggregator circuitry.
