Live payment terminals employing payment system public keys are evaluated. Dedicated test payment cards are internally issued by an operator of the payment system. Presentation of at least one of the cards to at least one of the terminals is facilitated. Testing the at least one of the terminals for proper management of the payment system public keys is facilitated. The testing can be in a test transaction conducted when the at least one of the cards is presented to the at least one of the terminals.
