Disclosed is a fresnel magnifying lens card holder dimensioned to fit standardized cards, for example, all credit card sized cards. The card holder features a pair of parallel tracks, for example, J-shaped tracks which face each other, and a raised narrow strip on a base plate thereby facilitating the slipping on and off all such cards and, at the same time, using the cards themselves as a carrier, as a storage place and as a delivering vehicle of the fresnel lens. That is, the holder can take advantage of the popularity of the standardized cards, using them as its carriers in delivering a fresnel magnifying lens and a data stripe shield to the credit card users. Since keeping the data stripe from damage and helping to see small print clearly make the card friendlier to the user, providing these benefits could be of significant importance to both the card using public and to those who are marketing products and services.
