Machine-readable data carrier

The invention relates to a machine-readable data carrier, for example in the form of banknotes, securities, postage stamps, personnel and membership cards, travel tickets, admission tickets, Credit cards, prepaid cards or check cards.

Such data carriers are known. For their detection or for protection against counterfeiting, they are provided with machine-readable features Mistake. The characteristics are the dimensions of the data carrier (width, length, thickness), its weight, its geometric shape, its color, its material and its surface properties are in question, for example the cross-sectional shape (corrugation or embossing) or surface roughness. Further features for recognition or forgery protection are imprints, specifically with regard to Shape and type of printing as well as the printing material including its color. Finally, perforations, watermarks used in the jfeterial or the arrangement of special parts or substances for identification. Except metal thread can be fluorescent, phosphorescent, magnet izable or radiating parts are arranged in the material or in the imprint, whereby the radiating parts can be such, which emit alpha, beta or gamma rays. In addition to the light transmission or the reflectivity of the data carrier can ultimately be its chemical properties as characteristics can be used for detection and / or against counterfeiting, as

chemical properties, for example its pH value, which can be checked non-destructively. The features described above can be combined with one another in any desired variety v / ground, in addition to their geometrical position, their size, their Form and its distribution on the base material of the data carrier are added as features. In particular, a flat data carrier can use the features listed above in dot form, line form., included flat or in any design.

While in the known prior art, all for the purpose of detection and / or machine-readable attached to protect against forgery Features are checked, the proposal according to the invention consists in attaching many machine-readable features of any type, but only a few to be checked, whereby the selection and the number of features to be checked can be changed. The test happens expediently according to the coordinates of the respective features by means of fixed sensors or according to the number of features Scanning by means of a sensor, past which the data carrier is guided line by line or which scans the data carrier line by line.

A data carrier according to the invention is characterized by a partial area for changeable and erasable information and a remaining area for fixed and unchangeable data, whereby the data carrier expediently made as a card made of paper, cardboard or plastic and on its back with a machine-readable strip is provided.

The advantage of the data carrier according to the invention is seen in that it is due to its large number of machine-readable features is absolutely forgery-proof and that for its identification only a relatively small number of the existing Features must be checked, these features being the respective Purpose can be selected accordingly.

In the drawing, a data carrier according to the invention is on
Example of a parking ticket shown.

The disk consists of a plastic card that holds a
has a rectangular basic format with bevelled corners. the
The surface of the card with a certain roughness is divided into a partial area 1 and two remaining areas 2. Machine-readable, unchangeable features are applied to the two remaining surfaces 2, which provide information about the publisher, the owner or user, the spatial and temporal scope and the intended purpose, which in the present case relates to the authorization to park a motor vehicle. on
the partial area Ij, which can be a strip of magnetizable material, for example, become changeable and erasable
Information applied, for example by magnetization.
This information can be, for example, an amount of money,
which is reduced by using different parking spaces belonging to the parking system according to the parked time.

The machine-readable data carrier can be used not only as a parking ticket, but also as a health insurance membership card to be provided with information at the doctor's office, or an authorization card for the use of legal-for-trade devices, the use of which is subject to a fee. It is important that the remaining areas 2
Contain invariable features, whereas the partial area 1 can be provided with variable measured values.

The characteristics listed in the introduction to the description are used machine readable features .in question. In addition to the geometric ι The shape of the data carrier is merely the attachment in the drawing indicated by openings 2a in a remaining area 2.
