Abstract
The utility model discloses an integrated passive radio frequency card, including a radio frequency card body, an electromagnetic coil and a chip set, wherein the electromagnetic coil and the chip set are packed in the radio frequency card body. the chip set is that a plurality of RI-R6C-001A chip parallel arrays are integrated in the radio frequency card body and share one electromagnetic coil; the chips of the chip set is corresponded to choosing switches one by one; the choosing switches select the chips of the chip set through a connection antenna, the connection antenna translates a received magnetic wave signal into an electrical signal and then send to the chips so as to read a designated chip. The passive radio frequency card has advantages of multiple functions of one card, convenient carry, simple preparation, and low cost; the passive radio frequency card can be widely used for relevant fields of pre-payment, e.g. water, electricity, heat and gas meter, and has good societal and economic benefits.
Description
Technical field
The utility model relates to a kind of integrating passive radio-frequency card.
Background technology
Radio-frequency card (RF card) is a kind of integrated circuit card that transmits data with wireless mode, it has the function of data processing and safety certification, be widely used in fields such as identity discriminating, credit discriminating, robotization control, safety precaution, its security, confidentiality, practicality are that various general strick precaution circuit are incomparable at present.
Radio-frequency card claims non-contact IC card again, it itself is passive body, when read write line when sticking into capable read-write operation, the signal that read write line sends is made up of two parts stack: a part is a power supply signal, after this signal is received by clamping, produce resonance with the L/C of itself, produce a transient energy and supply with chip operation; Another part combined data signal, commander's chip is finished data, modification, storage etc., and returns to read write line.Radio-frequency card inside is provided with the password card of special secret key number, and it utilizes the two-way radio radio-frequency technique, finishes the number identification of card.
In the prior art, the passive RF card mainly contains shell 1, and solenoid 2 and chip 3 formed (as shown in Figure 1), and a common radio-frequency card only has and contains a chip, need carry a plurality of cards when therefore going on a journey.So not only take big quantity space, take also and bring inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of integrating passive radio-frequency card, a plurality of chips are integrated on the radio-frequency card, have realized conserve space, purpose easy to carry, the function of " one card for multiple uses " has fundamentally reduced the cost of card, has good social and economic benefit.
The utility model for achieving the above object, the technical solution of employing is:
The integrating passive radio-frequency card comprises the radio-frequency card body, and solenoid and chipset, described solenoid and chipset are encapsulated in the radio-frequency card body; Described chipset is integrated in the radio-frequency card body by a plurality of RI-R6C-001A chip parallel arrays, a shared solenoid; Chip in the described chipset is corresponding one by one with selector switch; Described selector switch is by connecting the chip in the antenna connection chipset.The connection antenna transmits back chip after the magnetostatic wave signal that receives is converted into electric signal, reaches the purpose of the appointed chip of read-write.
Passive RF card described in the utility model can one card for multiple uses, easy to carry, and manufacture craft is simple, with low cost, can be widely used in other association areas such as water, electricity, heat, gas meter of pre-payment, has good society and economic benefit.
Description of drawings
Fig. 1 is the passive RF card structure synoptic diagram described in the background technology;
Fig. 2 is a kind of integrating passive radio-frequency card structural representation described in the utility model.
Embodiment
Be further described below in conjunction with 2 pairs of the utility model of accompanying drawing:
A kind of integrating passive radio-frequency card comprises radio-frequency card body 1, and solenoid 2 and chipset 3, described solenoid 2 and chipset 3 are encapsulated in radio-frequency card body interior 1.Described chipset 3 is integrated in the radio-frequency card body 1 by a plurality of RI-R6C-001A chip parallel arrays, a shared solenoid 2.Chip in the described chipset 3 is corresponding one by one with selector switch 4; Described selector switch 4 is by connecting day line options and the chip of specifying in the chipset 3.The connection antenna transmits back chip after the magnetostatic wave signal that receives is converted into electric signal, reaches the purpose of the appointed chip of read-write.
Passive RF card described in the utility model can one card for multiple uses, easy to carry, and manufacture craft is simple, with low cost, can be widely used in other association areas such as water, electricity, heat, gas meter of pre-payment, has good society and economic benefit.
