Abstract

PURPOSE:To allow the displaying of character information on a card and the rewriting of a display in correspondence to the use of the card by adding a magnetic capsule layer on the magnetic recording layer of the magnetic card. CONSTITUTION:The magnetic recording layer 2 coated with a mixture composed of a ferromagnetic material and a resin binder is provided on a resin base material 1. Further, the magnetic capsule layer 3 formed by dispersing magnetic particles in liquid, capsulating the liquid and mixing the capsules 8 formed in such a manner with a resin binder 9 is provided on the layer 2 to form the magnetic card. The particles 7 of the layer 3 are oriented according to the magnetic patterns of the layer 2 formed by a magnetic head, by which differences is generated in the transmittability of light in the capsules 8. As a result, a contrast in brightness and darkness is generated and the character information is displayed on the card. The visual reading of this information is possible. The display is automatically rewritten when the magnetic patterns are changed by the use of the card.

[Prior art and problems to be solved by the invention] Magnetic cards that are currently in widespread use include bripaid cards and bank cash cards. Although these cards can record information, they cannot visually display text information. There are very few devices that have the ability to display information. If these cards had a rewritable display function, it would be convenient to be able to display the balance.

Currently, in some cards, as shown in FIG. There is a method that displays by magnetizing iron powder according to a magnetization pattern. However, with this method, the ability to follow the magnetization pattern of iron particles is low, so in order to see the recorded contents, the card must be shaken to break up the iron powder each time, and the magnetic recording layer and transparent film must be separated. There were inconveniences such as an increase in manufacturing costs associated with the step of enclosing iron powder between the two.

On the other hand, there is a device called a mag viewer as a means for visually reading the magnetization pattern of a magnetic material. This is a colloidal solution in which magnetic particles are dispersed and sealed between glasses, or a colloidal solution in which magnetic particles are dispersed in a liquid and encapsulated, and coated on a sheet. This is what was written. When these mag viewers are brought close to a magnetized magnetic material, the magnetic particles (usually plate-shaped or needle-shaped) are oriented according to the turn of the magnetization, so a light and dark pattern appears on the mag viewer. Therefore, text information can be read.

However, once the mag viewer is removed from the magnetic material, the orientation of the magnetic particles is disrupted, making the pattern unclear. Therefore, in order to check the recorded contents of the card at any time,
You must always carry a magviewer with your card.
