a wireless transmission module;
one or more storage elements for storing a real account number and a secured account number associated with the real account number, the secured account number and the real account number being associated with the same account,wherein when the portable consumer device is interacting with a point-of-sale terminal to conduct a transaction, the portable consumer device;

determines which of the real account number and the secured account number stored on the portable consumer device to provide to the point-of-sale terminal based on whether the transaction is a proximity transaction;
when the transaction is a proximity transaction, operates in a proximity mode by wirelessly transmitting the secured account number instead of the real account number to the point-of-sale terminal via the wireless transmission module; and
when the transaction is not a proximity transaction, operates in a non-proximity mode by providing the real account number stored in a magnetic stripe to the point-of-sale-terminal,wherein non-proximity transactions conducted using the secured account number are denied.
