A financial transaction card includes an annunciator to generate a human perceptible indication upon activation. The annunciator may be audio, such as a pre-recorded sound, or may be visual, such as a light. The annunciator may be user-activated and/or may be activated upon use of the financial transaction card in a reading device. The annunciator, being relatively more difficult to implement than a conventional transaction card, serves to authenticate the card. Furthermore, the consumer appeal of a financial transaction card with such annunciator capability may be promoted by an issuer to attract new customers.
