1. A method of disabling and enabling a payment vehicle based on transmissions from a mobile telephone, the method implemented by a computing system comprising a transaction engine in a computer-based payment network that processes electronic payments, comprising:
receiving, by the computing system, a first text message from the mobile telephone, the first text message including a first command indicating that the payment vehicle is to be disabled;
disabling, by the transaction engine of the computing system of the computer-based payment network, the payment vehicle for subsequent payments in response to the first text message by updating logic of the computer-based payment network, the updated logic establishing additional security for the payment vehicle by automatically declining subsequent transactions involving the payment vehicle;
responsive to determining that a first payment authorization request for a first payment involves the payment vehicle, declining, by the transaction engine of the computing system of the computer-based payment network, the first payment authorization request that is being processed by the computer-based payment network according to the logic;
receiving, by the computing system, a second text message from the mobile telephone, the second text message including a second command indicating that the payment vehicle is to be enabled;
enabling, by the transaction engine of the computing system of the computer-based payment network, the payment vehicle for subsequent payments in response to the second text message by updating the logic of the computer-based payment network; and
authorizing, by the computing system, a second payment authorization request that is being processed by the computer-based payment network and that is for a second payment involving the payment vehicle according to the logic, wherein authorizing the second payment authorization request comprises connecting, by the transaction engine, the computer-based payment network to a source of funds corresponding to the payment vehicle.
