RU22904U1 - PLASTIC CARD - Google Patents

Abstract

A plastic card containing an insulating casing with a data carrier connected to the output terminals via communication lines, at least one of which is made with insulating gaps, and a removable key made in the form of an insulating substrate with reliefly protruding conductive jumpers spatially spaced adequately to line breaks, characterized in that the lines with gaps are placed on one of the walls of a flat channel, made inside the housing between its planes, and are coated with an electrically insulating th film, which has windows opposite the line breaks.

Description

Plastic card

. The utility model relates to information carriers, namely to plastic cards used for cashless payments for purchases, services or in banking operations.

Bank cards are known that contain a flat case (base) made of plastic non-magnetic and non-electrically conductive material with alphanumeric information deposited on its surface, individualizing the card to its owner (1).

The disadvantages of such cards are their low security against fraudulent actions with them in the event of a visual “theft of the card’s PIN code, and even more so if the card is transferred into the wrong hands.”

A credit card is known that contains an insulating casing with a storage medium placed in it, the communication lines of which have output gaps with the output contacts of the card, and a key made in the form of a substrate with conductive elements mounted on it, the number of which is equal to the number of breaks in communication lines spatially placed with the possibility of overlapping gaps, and the key is placed in the housing removably (2).

The specified credit card (2), taken as the closest analogue, has a low level of protection against intruders: the points of breaks in the communication lines of the information carrier with the output contacts are visually open, which makes it easy to bridge them, figuratively expressed as a “nail.

The technical result provided by the use of this utility model is the visual secrecy of secrets - breaks in communication lines and their recession relative to the plane of movement of the key in the case.

This technical result is achieved by the fact that in a plastic card containing an insulating casing with a storage medium connected to the output terminals of the card via communication lines, at least one of which is made with insulating breaks, and a removable key made in the form of an insulating substrate with relief protruding electrically conductive jumpers spatially spaced adequately to line breaks, the indicated connections with breaks are placed on one of the walls of a flat channel, made inside the core mustache between his planes, and are covered by an electrically insulating film, in which there are lines in front of the window breaks.

The accompanying drawings show: in FIG. 1 - card (general view with a section along a plane parallel to the plane of the card); figure 2 - General view of the key (rotated 180 °); in Fig.Z - section aa in Fig.1; figure 4 is a section bB in figure 2.

-2

The card contains a plastic case 1 with a data carrier fixed in it - a chip 2, the outputs of which are electrically connected via a communication line with terminals 4; a blind channel 5 is made in the housing, open from the end face of the housing 6; on one of the walls of the channel 5, fragments 7 of the electrically conductive track sequentially included in the gap of one of the communication lines 3 are fixed (by spraying or printing); fragments are separated, for example, by two electrically insulating breaks (gaps) 8 and closed by an insulating film 9, in which holes (windows) 10 are located opposite the breaks 8. The card is equipped with a separate key And, made in the form of a plastic substrate on which are electrically conductive protruding jumpers 12. The shape of the key 11 is adequate to the shape of the channel 5; the key is configured to be inserted into the channel 5 and then removed from it, while the jumpers 12 are spatially spaced identically to the location of the gaps 8 and the windows 10 of the film 9.

The card works as follows.

The key 11, being inserted into the channel 5 all the way through, jumpers 12 enters the window and shunts the breaks of 8 fragments 7 of line 3, thus connecting the terminal 4 to the chip. From this moment on, the card is ready for insertion into the card control device in order to read information from the chip.

The declared card is more fully protected from prying eyes, as the break points of the line are hidden in a blind channel, and the drownings of breaks of the contact line in the windows of the protective film prevent the gaps from being closed with a “nail”.
