Abstract
Cards may be provided with locked modes of operation. A card may, for example, monitor a particular sequence of one or more manual inputs while the card transitions from a low-power mode of operation to a locked mode of operation. The card may store the particular sequence of the one or more manual inputs as a locking code. The card may ignore subsequent manual inputs during the locked mode of operation until the locking code is reentered into the card. Once the locking code is reentered into the card, the card may again become reactive to manual inputs received by the card.
