CN202632338U - Radio frequency card - Google Patents

Abstract

The utility model discloses a radio frequency card which has convenient operation and can save electric energy. The radio frequency card comprises an outer shell, a chip mounted inside the outer shell, a coil wound outside the chip and a protective film coated on the shell; and the radio frequency card is characterized in that magnets are arranged in the coil, and the number of the magnets ranges from 1 to 10. When the radio frequency card approaches a magnetic sensitive switch installed near the card-reading coil, the magnetic field generated by the magnets on the card drives the magnetic sensitive switch near the card-reading coil to activate a device circuit, thereby realizing the card reading process, saving the electric quantity of the device, and bringing convenient for users.

Description

A kind of radio-frequency card

Technical field

The utility model relates to radio-frequency card, relates in particular to the radio-frequency card that is used for the pre-payment industry.

Background technology

At present, known radio-frequency card is made up of chip, coil, shell, during its work and the Card Reader coil generation induced potential that interacts.But the Card Reader coil links part generally by DC power supply with single-chip microcomputer, general employing lithium battery power supply in equipment such as pre-payment water power table, and the electric weight of lithium battery is limited; Long-time unlatching can cause waste of energy, so the deviser installs button in the prior art on card reader, when needing the equipment Card Reader; Press just Card Reader of button wake-up device; But the convenience that operates like this is relatively poor, especially at civilian instrument industry, because the user is unfamiliar with its operation; When the equipment of use, can increase the workload of equipment control side.

Summary of the invention

In order to solve above technical matters, it is a kind of easy to operate that the utility model provides, the radio-frequency card of saves energy; Comprise shell, chip in the enclosure is installed, be centered around the outer coil of chip; Be coated on the protective film on the shell, it is characterized in that being provided with in coil magnet.

Said magnet is 1～10.

The beneficial effect of the utility model is: near the magnet in this radio-frequency card and the Card Reader coil magnetosensitive switch of installation near the time; The magnetic field that magnet on the card produces makes the magnetosensitive switch activator circuitry of Card Reader coil annex; Realize the Card Reader process; Save the electric weight of equipment, made things convenient for the user simultaneously again.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified: shell-1, chip-2, coil-3, protective film-4, magnet-5.

Chip 2 is installed in the shell 1, and coil 3 is centered around outside the chip 2, and protective film 4 is coated on shell 1 outside, and magnet 5 is arranged in the coil 3.Near the magnetosensitive switch of installing magnet 5 in this radio-frequency card and the Card Reader coil near the time; The magnetic field that magnet 5 on the card produces makes the magnetosensitive switch activator circuitry of Card Reader coil annex; Realize the Card Reader process, saved the electric weight of equipment, made things convenient for the user simultaneously again.

Claims (2)

1. a radio-frequency card comprises shell (1), is installed in the chip (2) in the shell (1), is centered around the outer coil (3) of chip (2), is coated on the protective film (4) on the shell (1), it is characterized in that in coil (3), being provided with magnet (5).

2. according to the described radio-frequency card of claim 1, it is characterized in that said magnet (5) is 1～10.
