DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a cleaning card for magnetic track and chip card writing/reading devices which cleaning card includes a card shaped carrier partially coated with a soft cleaning material arranged on at least one pre-given surface area of the carrier.
BACKGROUND OF THE INVENTION
Cleaning cards for magnetic track writing/reading units, such as, for example, for automatic teller machines of banks and the like, are known and are, for example, described in DE-PS 35 38 223. In such cards, a cleaning felt is provided on one side of a card-shaped PVC carrier between two marginal codable magnetic strips, which felt, upon insertion of the cleaning card into the involved device, slides on the magnetic reading head of the device and cleans it. The cleaning effect can be improved by the preceding application of a cleaning fluid to the felt. However, the cleaning effect obtainable in this way is hardly sufficient to meet today's requirements. Moreover, such cleaning cards are practically unusable for chip card contact stations since a felt sliding along contact springs sensing the upper surface of the chip is not suited to effective cleaning of the contact sites.
A cleaning card is proposed in DE-C-196 22 287 in which a cleaning material carrying slide is built into a carrier corresponding to the chip card measurements, which slide after the insertion of the cleaning card into a writing/reading device can be moved back and forth to clean the contacts. This solution is expensive.
It is, therefore, the object of the present invention to provide a cleaning card, suited by simple means, to clean magnetic track writing and reading heads, as well as chip contact stations, in an absolutely reliable and optimal way.
SUMMARY OF THE INVENTION
The above-object of the invention is solved by a cleaning card of the previously-mentioned kind in accordance with the invention by using as the cleaning material a fiber flock which consists of closely arranged individual fibers of predetermined length and predetermined diameter adhesively attached to the carrier and extending essentially perpendicularly therefrom.
Such fiber flock fields achieve upon insertion of the card into the involved device a quasi-submergence of the magnetic track writing/reading head to be cleaned, as well as of the chip contact stations, into the packed individual fibers with a corresponding deep cleaning by way of a brushing effect.
In order to be able to use such a cleaning card universally with, for example, motorized magnetic card and chip card readers (hybrid readers), manual chip card readers, manual magnetic card plug-in readers, pass-through readers, infra-red readers and the like, the fiber flock cleaning material is preferably arranged, on at least one side of the card, at several pre-given surface areas corresponding to the different positions of the to-be-cleaned transmitting means of the involved devices. In connection with this, the individual fibers of the fiber flock cleaning material at the pre-given surface areas on one or the other side of the card can be of the same or different lengths and can be of the same or different diameters.
For cleaning a hybrid writing/reading device, which in addition to a magnetic head for the reading of magnetic strip; and in addition to a chip contact station for the contacting of chip contacts on a chip card, also has an optical sensor for capturing optical characteristics on an identity card, it is advantageous if a first surface area is associated with the chip contact station, a second surface area is associated with an optical sensor, and at least a third surface area is associated with a magnetic head of the writing/reading device.
In a hybrid writing/reading device of the previously-mentioned kind, the optical sensor consists of a fixed block in which a sensor eye is embedded. This embedded eye looks onto one side of identification cards and reads security records not recognizable with bare eyes. Because of the constructionally required recessing of the eye conce
