ABSTRACT Magnetic theory states that if something is to be shielded from a magnetic source then it should be surrounded on all four sides. This is consistent with magnetic theory, since it states that magnetic flux will flow around objects in space. It however makes for a very bulky and awkward device that would protect the credit card from demagnetization. In this invention the end of an envelope is open with a notch cut into it for the easy withdrawal of the credit card from the Card Shield. Current magnetic theory states that magnetic flux should find this opening and flow into the envelope, thus destroying the magnetic information inside. However protection is provided for the section of the credit card's magnetic strip that information isencoded upon. The magnetic flux that does reach the open end of the envelope is absorbed by the magnetic shielding material, thus saving the information. This advance in utility helps reduce the size of the shielding device while increasing the usability of the device. By using the plastic spacer in the device, it limits the Card Saver to one unit per card, thus ensuring that scratching of the card's magnetic strip does not occur. Don Pacey THE CARD SAVER
