Abstract
Systems and methods for providing secure electronic financial transactions are disclosed. Money is electronically stored on a plurality of smart cards. At least one smart card is equipped with an electronic security wall having a closed state and an open state. In the closed state, the smart card is disabled from participating in at least one financial transaction, and in the open state, the smart card may participate in at least one financial transaction. At least one smart card is equipped with at least one of a first security key for changing the state of the electronic security wall from the open state to the closed state, and a second security key for changing the state of the electronic security wall from the closed state to the open state. Financial transactions include, for example, electronically transferring money between a bank center and a smart card; electronically transferring money between the first and second smart cards; checking the amount of money stored on a smart card; and adding interest to the amount of money stored on the smart card.
