。(Prior art) Conventionally, a magnetic card such as a credit card or a cash dispenser card has an opaque card body made of a hard vinyl chloride material, and a transparent thin film covering made of a vinyl chloride material that covers the front and back surfaces of the card body. Display characters such as the credit card user and issue name are printed on the front side of the card body, and a magnetic film is embedded approximately along the longitudinal direction of the center. Identification symbols such as user number, password, amount, etc. are recorded on the card so that it can be identified only by a dedicated reader.
