FR2713058A1 - Protective sleeve for smart card, with warning of theft or leaving behind - Google Patents

Abstract

The protective sleeve (A) is made in the form of an envelope. The card (B) slips into the envelope. The envelope has two carbon contacts that are held apart while the card is in the envelope. A hybrid electronic circuit with surface-mounted components and powered by an integrated button cell is part of the envelope. The electronic circuit includes two delay timers, an astable multivibrator, an enabling circuit and a piezo- electric buzzer. The operating frequency of the astable multivibrator is calculated to correspond to the resonant frequency of the piezo-electric buzzer. The delay timers are started when the card is removed from the sleeve and stopped when the card is returned to the sleeve.

Description

The present invention relates to a protective case, electronic active

and

  warning against the loss, theft or forgetting of so-called "smart" or "magnetic" cards.

  Smart cards called bank cards (or others) and magnetic cards (access cards) are small and extra-flat. These are often stolen, lost or forgotten in computer reading devices.

  cards are in no way effectively protected against loss, theft or forgetting. The invention described below allows the neutralization of these three states.

  The present invention is in the form of a case (A), (1/3) made of anti-static plastic material (not restrictive) comprising a micro-electronic circuit composed of chips produced in hybrid technology (2/3) and ( 3/3), of a so-called armed fastener (C), (1/3), because it is more resistant to torsions exerted on it when using the said invention. two sensors (X and Y) (3/3) and (2/3) mounted on flexible plastic nipples with elastomeric typei5 shape memory. Note that the sensor Y is inside the case (A), (1/3) and that the said sensor will stop the travel of the card once it is engaged by a

  pressure on one of the walls of the case (A), (1/3). These two sensors are made of carbon mounted on rebounded nipples, in order to generate a contact which will cause an electrical impulse to activate the hybrid chip (2/3) and 20 (3/3). Note also the presence of surface mounted components (SMD) on the microelectronic circuit of said case (A) and (1/3).

  A first sensor (X), (3/3) located at the level of the reinforced fastener (C), (1/3) so that it is activated or deactivated during the tilting of the latter caused by pressure on the flexible nipple. 25 A second sensor (Y), (3/3) is located inside the case (A), (1/3) positioned so that it is activated or disabled, either by presence or absence

a card (B), (1/3).

  How it works: The user has two cases. 30 First case When the case (A), (1/3) extra-flat is removed either from its revolver pocket or from its wallet the sensor (X), (313) is released this allows an electrical contact (by its carbon surface) which will activate a piezoelectric buzzer (FP40), (3/3) which emits a first intermittent audible warning, for a short duration, also triggering a time delay (FP10), (3/3). In case of non-return of the case (A), (1/3) in the pocket or the wallet

  the user, the sensor (X), (3/3) not being switched, will activate the piezoelectric buzzer (FP40) which emits a second continuous audible warning.

  -2- When the smart or magnetic card (B) is removed, (1/3) housed in the case (A), (1/3) it releases a second sensor (Y), (3 / 3) located inside the case

  (A), (113). There is therefore an electrical contact via the carbon of the sensor, triggering a long-term delay (FP1 1), (3/3).

  The user then performs either a payment or any transaction using his released smart or magnetic card. After a while (more

  or less than one minute depending on the type of clock used), the time delay activity has expired, the piezoelectric buzzer (FP40), (3/3) will emit a continuous audible warning.

  To stop the buzzer (FP40), (3/3) which acts as an audible warning in case of forgetting, loss or theft of the card (B), (113) chip or magnetic. The user must return his card in its case (A), (1/3). It thus switches the second sensor (Y), (2/3) by pressure exerted on the stud comprising the sensor (Y). Then he must put the case (A), (1/3) in his revolver pocket or his wallet, in order to wedge the fastener (C), (1/3) which will rock the first sensor (X) , (3/3) by pressure exerted on the flexible stud comprising the said sensor. Once both

  sensors (X and Y), (3/3) tilted and only in this case the case (A), (1/3) will stop warning its user by means of the piezoelectric buzzer (FP40), ( 3/3) it will finally be silent since deactivated.

  The user can therefore neither have their card (A), (1/3) chip or magnetic stolen, nor forget it because the said case will warn him by its piezoelectric buzzer (FP40), (3 / 3)

  as long as the two sensors (X and Y), (3/3) will not be tilted by pressures exerted on the flexible pins comprising the said sensors.

Second scenario.

  If only the card (B), (1/3) is removed from the case (A), (1/3) leaving the piezoelectric buzzer (FP40) in the pocket or wallet, (3 / 3) will emit by means of the sensor (Y), (3/3) housed in the case (A), (3/3) an intermittent sound signal of short duration, a long delay is triggered (FP1 1), (3/3). The user will make a payment or an operation using his card (B), (1/3). After a certain time plus or minus one minute, the clock (2/3 and 3/3) will activate the piezoelectric buzzer (FP40), (3/3) which will emit a continuous audible warning. To stop the so-called buzzer, which acts as an audible warning of loss or forgetfulness, the user must quickly put away his card (B), (1/3) in its case (A), (1 / 3) 35 it thus switches the second sensor (Y), (313) the two sensors (X and Y), (3/3) being tilted by pressure exerted on the flexible nipples comprising the said

  sensors, the buzzer (FP40), (3/3) therefore remains silent again.

  (FP40) piezoelectric type, an astable multivibrator (FP20).

  The device being electronic, it will have to be powered autonomously by a button cell (not restrictive) which will aim to power the hybrid circuit (2/3 and 3/3), the surface mounted components (CMS) dependent and the

  piezoelectric buzzer (FP40), (313).

  The frequency of the astable multivibrator (FP20), (3/3) will be calculated so as to

  be tuned to the resonance frequency of the piezoelectric buzzer (FP40), (3/3).

  For energy saving reasons, only part of the hybrid chip (2/3 and 3/3) will be powered to detect the activation of the sensors (X and Y), (3/3). If there is activation of one of the said sensors, the small part of the hybrid (2/3 and 3/3) which

  is supplied with energy in turn triggers via a transistor (QI), (2/3) (CMS) the supply of the entire hybrid chip (see 2/3).

  The technology of the chips used for the realization of the hybrid (2/3) is linked

  HCMOS type due to its low consumption, switching speed and fan out.
