A method of verifying authority of a customer to use a financial instrument, includes initiating one or more transactions using a financial instrument identified by a customer. One or more attributes of the initiated one or more transactions are stored. A determination is made as to whether or not a further financial transaction using the identified financial instrument, requested by the customer prior to acceptance of the use of the financial instrument, complies with pre-acceptance transaction rules. The further transaction is initiated only if it is determined to comply with the pre-acceptance transaction rules. One or more proffered attributes are received, typically from the customer. The received proffered attributes are compared to the stored attributes. Use of the financial instrument by the customer is then accepted if the received proffered attributes correspond to the stored attributes.
