Device for protecting magnetic cards and method of making same

摘要

A protective card case or sheath for a single card having a magnetically encoded strip is in the form of a generally rectangular, flat, sleeve-type holder. The sheath has a protective strip along the top and bottom area of a front and rear panel for protection of the data encoded strip of a credit card or the like regardless of the orientation of the card in the holder. The protective strips thus shield the magnetically recorded data from magnetic and electric fields which might otherwise erase or damage such magnetically stored data. The card holder also includes a lengthwise centrally disposed transparent area in both the front and rear panel to enable observation of the identifying number imprinted on the card. The card holder also includes a screened area or stripe along the top and bottom areas of the front and rear panels on which informational material can be printed. The card holding device is constructed by cutting and sealing dies to cut and seal inner and outer layers of clear polyvinylchloride which are assembled and sealed to form front and rear panels which are then assembled and sealed along three edges with one edge left open for insertion and removal of the encoded card. A third transparent panel may also be sealed around three sides over the rear panel to form a pocket for receiving an information bearing card.
