BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a data transmission device comprising a unit formed of a identification card and its holder enclosure wherein the stored data is read by a distant reading device.
BACKGROUND OF THE INVENTION
At present more and more data transmission devices are being introduced which are small sized devices comprising active and passive data, for example so-called smart cards where a micro chip has been disclosed in a card like a credit card or bank card. The data in the micro chip has to be unloaded and correspondingly the additional data or changed data has to be fed to the card with a suitable reading device. In the latest type of cards the reading is conducted by passing the card at a distance from the reading device. This kind of application is simple and fast because the card does not have to be inserted into the reading device itself but it is sufficient that the user for example passes the reading device whereby the reading device reads the data in the micro chip and changes it simultaneously. These kind of applications are being tested as means of payment in collective transportation systems. The card can of course also be applied to many other purposes, for example, as an identification card an employer to control working hours, simultaneously functioning as an identification card. At the same time the card can be provided with a person's photograph whereby with the assistance of the computer Connected to the control system the corresponding photo appears in the monitor. Thus the personal data and the appearance can be compared to the data on the card.
To equip a thin card with the necessary source of information as well as transmission and receiving means may be difficult. Further the used card cannot be reused if the appearing data is changing, for example if the employee quits the job, the card is useless even if the data can be reprogrammed but the data printed on the card remains the same.
SUMMARY OF THE INVENTION
The aim of the present invention is to create a more advantageuos data transmission device which can be used again and again simply by reprogramming the chip in the card. This is achieved according to the invention with an identification card, which as known per se is provided with the desired identification data whereas the holder card to which the identification card is attached is provided with the transmission/receiving means and storing means for the data intended for cooperation with the corresponding means of the reading device. the manufacture of such a holding card is simple. The holder is usually made of a casing-like part with a closed bottom. In this bottom a recess is made encircling said bottom, in which recess the induction coil functioning as a transmitter and a receiver is arranged, said coil also being connected to the micro chip embedded in the bottom. These transmission and receiving means as well as the recording means are known per se and described for example in U.S. Pat. No. 4,572,776 and PCT application WO 85/03831. It is clear that the means may have other practical solutions, essentially, that the invention consists of a unit comprising a conventional card and a holder thereof provided with receiving and transmission means known per se.
The holder may be like a casing, the bottom of which is equipped with the data transmission and recording means and covered by a protective coating. Over this coating the card is pushed in the usual manner into position and the casing can, by suitable clamp or fastening means, e.g., a needle or the like, be fastened on the garment or the casing can hang around the neck with a suitable chain. In this connection the term "casing" means all kinds of holding or supporting means for conventional plastic cards.
