Abstract

The utility model belongs to a technique of intelligent card, and relates to an external non-contact type radio-frequency card. In the prior-art IC card used for charging, packing a permanent magnet is adopted and reed switches in a meter are matched for realizing arousing. This card does not satisfy the requirement to the standard card in ISO7816-1 in packaging, the data reliability is affected in reading and writing and other magnetic cards are easily magnetized by the IC card. The utility model provides an external non-contact type radio-frequency card which is packed with one piece or a plurality of pieces of combined magnetic conductors, which are arranged with a network parallel array or a polygonal shape and are manufactured by magnetic conductive material. The magnetic conductors and magnetic switched are adopted for realizing arousing. Not only can the packing thickness of the utility model satisfy the requirement of standard card and stable and reliable data reading-writing transmission obtained, but also other cards are not magnetized in storing. The external non-contact type radio-frequency card can be widely used for the non-contact identification device of the fieldsof prepaid water, electricity, heat and gas meters, and other related fields, and has better social and economic benefits.

Description

A kind of external non-contact radio-frequency card

Technical field

The utility model belongs to smart card techniques, relates to a kind of radio-frequency card, specifically refers to a kind of external non-contact radio-frequency card.

Background technology

Radio-frequency card claims non-contact IC card again, it is successfully radio frequency to be known technology and the IC-card technology combines, solved passive (non-transformer in the card) and exempted to contact this difficult problem, it is a quantum jump of field of electronic devices, owing to exist magnetic card and the incomparable advantage of Contact Type Ic Card, therefore make it once appearance, just cause immediately widely and pay close attention to, and applied with surprising rapidity.Existing radio-frequency card kind is more, for example be applied to the IC-card that various buses, water meter, ammeter, natural gas meter etc. charge, yet for the awake technology of changing between card and the read-write equipment, all be provided with permanent magnet on the general IC-card that uses, and the tongue tube in the cooperation table realizes waking up, therefore makes this kind IC-card have the some shortcomings part in encapsulation and read-write:

1, because encapsulation permanent magnet in the card, cause the package thickness of card generally not meet among the ISO7816-1 to the requirement of standard card, therefore can only be made into nonstandard card, can not use general read write line;

2, permanent magnet is encapsulated in the card, if card and bank card or some other magnetic stripe card are often deposited together, usually can cause the magnetization of bank card or magnet card, makes its damage;

3, when read-write card, permanent magnet can apply harmful magnetic field to radio-frequency antenna, and reading card and data cause interference, influence stability of data transmission, reliability, bring inconvenience to the user.

The utility model content

The technical problems to be solved in the utility model provides a kind of external non-contact radio-frequency card, and it not only can reach the requirement that standard card is made, and deposits Shi Buhui other cards are caused magnetization, and read-write transmission data stabilization, reliable.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of external non-contact radio-frequency card comprises the radio-frequency card body, it is characterized in that: described radio-frequency card body is provided with magnetic conductor.

Above-mentioned magnetic conductor is monolithic or multi-disc combination.

Above-mentioned magnetic conductor is that netted parallel array or polygon are arranged.

Above-mentioned magnetic conductor is encapsulated in the radio-frequency card inner chamber.

Above-mentioned magnetic conductor adopts iron, ferroalloy, nickel, cobalt, silicon steel or sloping magnetic conductive material to make.

Compared with prior art, following advantage of the utility model tool and effect:

1, adopt the encapsulation magnetic conductor, its card body package thickness can meet the requirement of ISO7816-1 to standard card fully, uses general card reader/writer;

When 2, the nonmagnetic release of magnetic conductor and other magnetic cards are deposited, can not cause magnetization together, and can not apply harmful magnetic field during read-write card, can not influence reading and transmitting of data to radio-frequency antenna to other magnetic cards;

3, manufacture craft is simple, with low cost, can be widely used in the contactless recognition device of other association areas such as water, electricity, heat, gas meter of pre-payment, has good social and economic benefit.

Embodiment

Referring to Fig. 1, Fig. 2, a kind of external non-contact radio-frequency card, a kind of external non-contact radio-frequency card, form by a radio-frequency card body 1 and a magnetic conductor 2, wherein magnetic conductor 2 is encapsulated in the radio-frequency card inner chamber 3, and magnetic conductor 2 adopts iron, ferroalloy, nickel, cobalt, silicon steel or slope to have the material of magnetic conductivity; Referring to Fig. 3, Fig. 4, magnetic conductor 2 can be encapsulated in radio-frequency card inner chamber 3 or multi-disc assembled package radio-frequency card inner chamber 3 by monolithic, and the combination of its monolithic or multi-disc can be adopted netted parallel array or polygon arrangement mode.

During use, can assemble the magnetic switch device in table, the magnetic conductor in the radio-frequency card can change awake function by contactless closed realization of magnetic switch device that cause, and is convenient and swift.
