Abstract
Abstract In the technical field of known cardholders for devices such as cards with magnetic stripes on which is encoded information and or data in the form of patterns of magnetism, the known cardholders offer no method of `keeping` (in magnetism terminology) the magnetic patterns. The present invention is characterised by incorporating into the cardholders, keepers in the form of sheets of magnetically soft ferromagnetic material with high resistance. The benefit of the invention is obtained when devices are placed with the reading surface of their magnetized stripes in close contact with the surface of the ferromagnetic material which, making use of known properties of the material, then acts as keeper of the magnetic patterns.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
129 words
A cardholder incorporating at least one sheet of magnetically soft ferromagnetic material, wherein each of said at least one sheet is a keeper means for maintaining at least one pattern of magnetism carried in at least one stripe on at least one card to be housed in said cardholder, each sheet being dimensioned to match each at least one stripe relative to which it functions as a keeper, each sheet comprising a magnetically soft ferrogmagnetic material which has a high resistance to eddy currents and having at least one surface which is a smooth, low friction surface, said cardholder being so constructed that a reading surface of each card which is housed therein when in use will normally be in close magnetic proximity the keeper afforded by the sheet.
Claim 2
Dependent Claim
129 words
A cardholder incorporating at least one sheet of magnetically soft ferromagnetic material, wherein each of said at least one sheet is a keeper means for maintaining at least one pattern of magnetism carried in at least one stripe on at least one card to be housed in said cardholder, each sheet being dimensioned to match each at least one stripe relative to which it functions as a keeper, each sheet comprising a magnetically soft ferrogmagnetic material which has a high resistance to eddy currents and having at least one surface which is a smooth, low friction surface, said cardholder being so constructed that a reading surface of each card which is housed therein when in use will normally be in close magnetic proximity the keeper afforded by the sheet.
