A luminescent card device has a luminescent card and an actuator. The luminescent card has a plastic layer, a luminescent layer, a memory device and multiple printed layers. The actuator is mounted on a comer of the luminescent card and selectively transforms direct current into alternating current that drives a capacitor embedded in the luminescent layer to excite the luminescent layer and make it emit light. Only a few specific manufacturers make the luminescent layer so if criminals try to counterfeit any luminescent card device, law enforcement agents are able to trace the criminals through the luminescent layer's manufacturers. The issuing banks and card companies do not lose money from any counterfeit cards.
