Abstract: A card having an antenna, one or processors, and memory having stored thereon a first application and a second application configured to receive an input of the card and determine a request associated with the input. The card is further configured to activate, responsive to determining that the request is consistent with a contactless EuroPay-MasterCard-Visa (EMV) data standard, the first application. The first application is configured to communicate, via near field communication (NFC), data to the communicating device via the antenna based on the EMV data standard for payment purposes. The card is further configured to activate, responsive to determining that the request is consistent with a near field communication data exchange format (NDEF) standard, the second application. The second application is configured to communicate, via NFC, data to the communicating device via the antenna based on the NDEF standard for verification/identification purposes.
