DE4210149A1 - IC data card with data exchange - has card with edge features to identify type of reading device required - Google Patents

Abstract

The IC data card contains embedded IC circuitry and is produced of plastic. Chip cards may be various types that involve data exchanges using non-contact and contact methods of reading. The type of card is identified by physical features, such as an angled corner (4) or a recess (3). The feature can be identified by some form of sensing which can be a mechanical contact. The information on any magnetic strip (7) may also be accessed. USE/ADVANTAGE - for credit card or telephone charge card. Simplifies identification of type of data exchange required.

Description

As development continues, new ver drive invented for data storage and data exchange.

The use of plastic cards as credit cards, bank cards has experienced many phases up to phone cards. Bar code, magnet stripes and holographic records were made using smart cards replaced, which contain electronic memory and microchips. Contactless chip cards have recently come onto the market.

To z. B. with phone cards already in use reading devices in the public telephone booths to new procedures to be able to provide, at least new chip cards and readers be temporarily compatible for both procedures.

According to the invention, this object is achieved in that Chip card, especially with contactless chip cards, at which cannot be electrically sensed, mechanical Markings are present, which the reader on the ge Switch the desired data exchange procedure.

According to the invention, this can be notches, holes or similar marks on the chip card.  

But it is also important that in the readers, which so far the holographic or magnetic record changed ha ben (such as for phone cards to debit the fees), one Lock is present, which when switching to reading from Chip cards completely or partially prevent such changes.

Fig. 1 shows examples of such labels according to the invention to a contactless smart card (1). This can be holes ( 2 ) or notches ( 3 ) on the circumference of the chip card ( 1 ). Beveled corners ( 4 ) or similar changes in shape also fulfill the object of the invention.

The markings are scanned in the readers by contacts ( 5 ) or sensors and switch e.g. B. in the presence of such cher markings on the reading of contactless smart cards.

Fig. 1 shows the contact ( 5 ) closed.

This is expediently the function "chip card" of the Lesege advises. If there are no notches ( 3 ), this corresponds to the cards already in circulation of the previous version, e.g. B. with magnetic stripes.

In Fig. 1, for example, an erase head ( 6 ) of a reading device is indicated schematically, which erases or changes data on the magnetic stripe ( 7 ) during magnetic recording.

According to the invention, it is recommended that such a device at Um switching to electronic storage entirely or at least in turn off an area because a chip card keeps repeating can be used and a deletion of the records does not is casual.  

Given the large number of possible designs of reading devices, the illustration in FIG. 1 can only serve as an aid for a better understanding of the inventive concept and as an suggestion for the constructive design, but not in a limiting manner.

Claims (3)

1. Methods and devices for data exchange with Chipkar th, which also other data carriers such. B. in the form of hologram markings, characterized in that the chip cards have mechanical markings which switch the reader to the desired data exchange method. 2. The method and devices according to claim 1, characterized characterized that as a mechanical marking There are notches or holes in the chip card. 3. The method and devices according to claim 1, characterized characterized in that readers, which change the holographic or magnetic records If there is a lock, which is available when switching to reading smart cards such changes entirely or partially prevented.
