Abstract
A wireless financial transaction instrument, such as a card, has a magnetic stripe, a display, and an on-board power supply, such as a battery, and is usable with a dual capture point of sale terminal. Information is received by such a terminal from the card wirelessly, and also from the magnetic stripe, and the data received contactlessly is preferably used to verify that read from the stripe. The display can display the account number on command, or to display a current balance, or amount of credit remaining, or any combination of these items of information.
