Abstract
A card that carries information on it and a card reader that read and/or writes information on the card. The card is made of a fluorescent material that, when receiving UV light, emits light in the visible spectrum. The card reader may have a UV lamp for illuminating the card. The card, illuminated by the UV lamp, glows at a desired state of the card read/write operation. If the card reader is a contactless reader, the reader will irradiate UV light to the card brought in close proximity to the reader. Illuminated by the UV light, the card glows in the hand of a cardholder.
