Description

RFID jam-proof smart card subsides

Technical Field

The utility model relates to an entrance guard's card technical field specifically is a RFID jam-proof smart card subsides.

Background

RFID-Radio Frequency Identification (RFID) is an abbreviation for Radio Frequency Identification. The principle is that non-contact data communication is carried out between the reader and the tag, so that the aim of identifying the target is fulfilled. The application of RFID is very wide, and the typical applications at present include animal wafer, automobile wafer burglar alarm, entrance guard control, parking lot control, production line automation and material management.

Access systems have been widely used among others: residential housing, office buildings, corporate door access, elevators, fingerprints, membership cards, etc.; most of the existing entrance guard induction cards are carried by a plastic card or a plastic piece.

The entrance guard's response card on the existing market still has as follows not enough:

1. the metal resistance and the antimagnetic performance are poor, and the interference of a metal shell of a mobile phone, a battery of the mobile phone or an SIM card of the mobile phone on a coil cannot be effectively shielded, which is the reason that a common induction card cannot work because the common induction card is directly put into a mobile phone shell.

2. The induction card is inconvenient to carry and use, the induction card is sometimes placed in a wallet, the induction card cannot be seen, sometimes the induction card cannot be known, the induction card is placed in a bag and sometimes placed together with a mobile phone, metal resistance or antimagnetic performance cannot be achieved, sometimes the induction card is found not to be magnetized when the induction card is used, the memorability of the old and children is not good, and the entrance guard card is easily lost.

Preferably, the thickness of the RFID tamper-proof smart card sticker is 0.9 mm.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the thickness is only 0.9mm, the ultra-thin type, paste in cell-phone back, if handheld feel is like there is not. Occupies no space and is easy to carry.

2. Ferrite anti-interference sheet, 0.08mm permeance reaches surprisingly 150 mu. The traditional wave-absorbing material is thick, and the magnetic conductance is low when the thickness is more than 0.12 mm.

3. Multiple types of protocol chips can be embedded simultaneously.

4. The 3M adhesive tape is arranged on the back of the smart card sticker, is convenient to carry, and can be pasted on a mobile phone shell, a schoolbag or clothes.

5. Pure copper coil welding, shielding prevention and metal resistance materials are adopted, and high-speed reading and writing are realized.

6. The compatibility rate is high, and the method is used for: residential housing, office building, company entrance guard, elevator, fingerprint, membership card, etc., and the usage can also be used for material identification, such as many building materials in a construction site, and can also be used for identifying statistics respectively.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: an RFID anti-interference smart card sticker comprises a pure copper wire welding chip layer 1, wherein the pure copper wire welding chip layer 1 is welded by adopting a pure copper coil and has the advantages of shielding prevention, metal material resistance and high-speed reading and writing, a PP (polypropylene) environment-friendly printing material layer 2 covers the upper surface of the pure copper wire welding chip layer 1, the card sticker is more attractive, elegant and three-dimensional due to the arrangement of the PP environment-friendly printing material layer 2, a ferrite anti-interference chip layer 3 covers the lower surface of the pure copper wire welding chip layer 1, the ferrite anti-interference chip layer 3 is made of 0.08mm ferrite anti-interference material, because an induction card works through the magnetic field coupling of the coil, the strength and the direction of a magnetic field are greatly interfered by metal, a mobile phone battery and internal components are provided with a large amount of metal, particularly, the rear cover of a mobile phone is fully covered by metal, the interference is fatal to the work of the induction card, and is the main reason that the traditional induction card cannot work normally when being directly, therefore, the anti-metal anti-magnetic layer is added to solve the problem, and the ferrite anti-interference wave-absorbing material is arranged, so that the anti-magnetic performance of the card sticker is good, the interference of a metal shell of a mobile phone, a battery of the mobile phone or an SIM card of the mobile phone to a coil card can be shielded, wherein the ferrite is of a black glittering crystal-shaped block structure, the magnetic conductivity reaches 150 mu, and the traditional wave-absorbing material is gray and matt, although the cost is low, the thickness is thicker and larger than 0.12mm, the magnetic conductivity is low, the shielding performance is poor, the back 3M strong adhesive layer 4 covers the lower surface of the anti-interference ferrite sheet layer 3, and the back 3M strong adhesive layer 4 is arranged to enable the card sticker to be more firmly pasted and not easy to separate, and is convenient to. The sizes of the pure copper wire welding chip layer 1, the PP environment-friendly printing material layer 2, the ferrite anti-interference layer 3 and the back 3M strong glue pasting layer 4 are all consistent, and the diameters are about 40 mm and 50mm, so that the size is small, the occupied space is small, and the carrying is easy. The overall shape of the card paste can be regular, such as square, rectangle, diamond, circle, etc., or irregular. The card body is an ultra-thin type with the thickness of 0.9mm, is stuck on the back of the mobile phone, and can be held by hands if the card body is not so thin.

The working principle is as follows: when the RFID anti-interference smart card sticker is used, the film on the back 3M strong adhesive layer 4 is uncovered, and then the card sticker is attached to the back of equipment.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
