Abstract
The utility model discloses a non-contact card with an acknowledging device, belonging to the field of non-contact cards. The non-contact card comprises a card chip and an antenna resonant circuit, and also comprises an acknowledging device used for providing a card holder to acknowledge operation orders of the card and then to send the acknowledged information to the card chip. The acknowledging device is positioned at the outer of the antenna resonant circuit and is connected with an I/O interface of the card chip. The utility model is characterized in that the acknowledging device is connected to the I/O interface of the card chip, which is used for the card holder to acknowledge the operation orders of the card and then to send the acknowledged information to the card chip, thereby the card holder can control the autonomy of responding the operation orders of the card, preventing the information in the card from being secretly swiped or the incorrect manipulation of the card. Simultaneously, because the antenna resonant circuit is always in a stable state, the resistance factors are eliminated, the continuity of the antenna resonant circuit is strengthened, and the operation of the card holder becomes convenient.
Description
Technical field
The utility model relates to the non-contact card field, is meant the contactless card of band affirmation device especially.
Background technology
Contactless card, i.e. radio-frequency card or contactless card, it successfully combines REID, has solved passively to contact this difficult problem with exempting from, be a quantum jump of field of electronic devices.
Contactless card also has the following advantages except original characteristics of contact card:
1) swift to operate: as to be wireless telecommunications between card and card reader, the user need not plug-in card during use, the also fixing direction of card, only need in effectively reading the district, card reader (general 5-10CM) card be flashed gently, just will block in the internal information input card reader or the corresponding card of execution operational order in card, improve operating speed greatly, be applicable to quick, high flow capacity place;
2) anti-interference: have anti-collision mechanism in the contactless card, when many cards enter the working range of read write line simultaneously, can prevent to occur between the card data and disturb, allow many cards to operate simultaneously;
3) high reliability: do not have machinery between contactless card and the read write line and contact, avoided because the various faults that the contact read write line produces, need not worry the contact damage simultaneously or come off and cause card inefficacy, the life-span of having improved application reliability and equipment and card;
4) high security: the chip itself that contactless card uses is a safety chip, its action need cipher control, and also its communication process encrypts, so guaranteed its security;
5) multiple application: the characteristics of contactless card storage organization make it can one card for multiple uses, can be applied to different systems or occasion.As the management domains such as (public transport, bankcard consumption etc.), work attendance, gate inhibition of paying dues.
The above-mentioned advantage of contactless card has been brought a lot of facilities to the user, but along with the continuous expansion of its application, contactless card more and more is applied to consumption, and at this moment, the advantage of its high security will inevitably be queried.Though the sequence number of contactless card is unique, has alterability again, contactless card and read write line will carry out three second phases and recognize each other card during use, and all data are all encrypted in communication process, also all there is operator password and the access consideration of oneself each sector in the card, but because it has the advantage of " only need (general 5-10CM) card be flashed gently; just will block internal information input card reader " in card reader is effectively read the district, the holder is stored in the information in the card, cash particularly, be easy to and under the unwitting situation of holder, stolen brush, cause damage to the holder by non-holder (having the card reader that is complementary with contactless card).
When some non-contact cards and card reader communication, just in card, carry out corresponding card operational order, and output card internal information not, in this case, if the card reader that will be complementary with non-contact card is stealthily near non-contact card, non-contact card just can be carried out corresponding card operational order, also can make troubles and loses to the holder.
Above-mentioned shortcoming at non-contact card; existing solution is: be connected installing one on-off circuit on the lead between the core of the card sheet and aerial coil; the autonomy that is used to make the output of holder's control card internal information or in card, carries out the associated card operational order; the private ownership of information in the protection card has prevented the maloperation of card stolen brush of internal information or card.
But existing solution is not that perfectly its weak point is: when on-off circuit was closed, because the reason of impedance, the conduction in antenna resonance loop was bad, was not easy to holder's operation.
The utility model content
In order to overcome in the prior art, in the time of on the connection lead of on-off circuit between the core of the card sheet and aerial coil, its antenna resonance loop conduction is bad, and the not high problem of ease for use, and it is a kind of with the contactless card of confirming device that the utility model provides.
The technical scheme that the utility model provides is: a kind of contactless card, comprise the core of the card sheet and antenna resonance circuit, it is characterized in that, described contactless card comprises that also is used for the affirmation device that the confession holder confirms the card operational order and confirmation sent to the core of the card sheet, described affirmation device is positioned at outside the described antenna resonance circuit, and links to each other with the I/O interface of the core of the card sheet.
Described affirmation device comprises mechanical switch, sensor devices, audio-switch, body temperature inductor, pressure inductor, vibration transducer, acceleration transducer, magnetic sensors or electric field induction device.
The beneficial effects of the utility model: be connected on the I/O interface of the core of the card sheet by confirming device, be used for confirming the card operational order and confirmation being sent to the core of the card sheet for the holder, make the autonomy that the holder can control response card operational order, prevented the maloperation of card stolen brush of internal information or card, simultaneously, because antenna resonance circuit is in steady state (SS) always, thereby got rid of impedance factors, strengthen the conduction in antenna resonance loop, made things convenient for holder's operation.
