Claim 0:
1. A smart card-to-card contactless payment system comprising:
a first active stored-value smart card (“SVSC”) being an initiator of a transaction;
a second active SVSC being a target of the transaction;
each of the first active SVSC and the second active SVSC comprising:
an active near field communication (“NFC”) reader enabling a direct wireless communication between the first active SVSC and the second active SVSC when the first active SVSC is within a pre-determined distance to the second active SVSC;
an NFC tag for storing data, the NFC tag being a re-writable tag, the stored data including a stored value and card ID data;
a microprocessor enabling processing, storing and transmitting the card ID data;
a battery for powering the NFC reader;
a keypad comprising a display and numerical keys, the numerical keys configured to accept input of a personal identification number and a transaction amount, the keypad being maintained in a deactivated state pending activation; and
a display connector configured to intermediate between the keypad, the display and the microprocessor;, wherein, when the first active SVSC is within the pre-determined distance of the second active SVSC:
the keypad on the first active SVSC is configured to be activated in response to a receipt of input of one or more numerical keys on the keypad, the one or more numerical keys being equal to a one or more pre-determined numerical keys;
a security of the direct wireless communication is confirmed between the first active SVSC and the second active SVSC by:
retrieving, via the active NFC reader associated with the first active SVSC, card ID data associated with the second active SVSC wherein the card ID data associated with the second active SVSC includes a name of a cardholder associated with the second active SVSC;
acknowledging and confirming the card ID data associated with the second active SVSC by the microprocessor embedded in the first active SVSC, wherein acknowledging and confirming the card ID data associated with the second active SVSC comprises:
displaying the name of the cardholder associated with the second active SVSC on the display of the first active SVSC;
receiving, via the keypad located on the first active SVSC, authentication of the cardholder associated with the second active SVSC from a cardholder associated with the first active SVSC; and
retrieving, by the active NFC reader associated with the second active SVSC, card ID data associated with the first active SVSC and the transaction amount, from the first active SVSC, wherein the card ID data associated with the first active SVSC includes the name of the cardholder associated with the first active SVSC; and

acknowledging and confirming the card ID data associated with the first active SVSC by the microprocessor embedded in the second active SVSC, wherein acknowledging and confirming the card ID data associated with the first active SVSC comprises:
displaying the name of the cardholder associated with the first active SVSC on the display of the second active SVSC;
receiving, via the keypad located on the second active SVSC, authentication of the cardholder associated with the first active SVSC from the cardholder associated with the second active SVSC; and

in response to the acknowledging, the transaction is completed between the first active SVSC and the second active SVSC.
