Description

Switching Access Card {SWITCHING ACCESS CARD}

The present invention relates to a switching access card.

More specifically, it is applied to various cards, and the induction electromotive force from the card reader is energized in the loop coil only when the user presses the switching button every time the card is used, thereby reading the card and turning on the LED to indicate the use of the card. So that it relates to one switching access card.

In general, a smart card is a chip card with a built-in microchip for logical operation, and is widely used as a financial card, a transportation card, and a network access card. A memory card is a card with a chip such as a smart card. However, as a card that performs only a function of storing data, it is used in a prepaid calling card, an item purchasing card, and the like.

In this case, an IC (Integrated Circuit) card is used as a broad term including the smart card and the memory card. In other words, the IC card has been used for various purposes in various fields such as telecommunications, finance, transportation, and e-commerce since the 1990s, and is rapidly growing due to the rapid increase in the use of the Internet and changes in the information and communication environment. In particular, based on the development of semiconductor and software technologies, IC card application fields are expanding by securing high-capacity information recording capability and high reliability security that conventional magnetic stripes do not have.

On the other hand, the memory card, as described above, is a card without a microchip and has only a memory, and is not a smart card in a strict sense, but is broadly included in the smart card.

In addition, the smart card and the IC card may be used in the same sense, hereinafter will be described as a smart card for convenience of description. In this case, the smart card refers to a card capable of performing advanced functions such as determination, operation, and data protection by embedding a microchip as described above.

The smart card is divided into two types according to the communication method with the outside, a contact card for transmitting and receiving data through the contact exposed to the surface of the card and a contactless type for transmitting and receiving data wirelessly using the built-in loop coil. Can be divided into cards. At this time, in the case of a contact card is inserted into the card reader, in the case of a non-contact card is exchanged by bringing the information near the contactless card reader.

In addition, the smart card can be divided into two types according to the contention type, which is a hybrid type in which a contact and a contactless chip exist in one card, and a contact and a contactless type in a single card. It can be divided into a combination type which exists.

On the other hand, there are no batteries in these various types of smart cards, and power is provided from the outside by the reader. In particular, in the case of a smart card (contactless card, hybrid type, and combination type) that transmits and receives data wirelessly using a built-in loop coil, the contacts formed at both ends of the loop coil and the contacts drawn from the microchip are conductive adhesives. It adheres by and becomes energized.

Such cards are usually stored in wallets. If you have more than one card, there is a risk that the card reader reads each card and collects the charges on all cards. In the case of a contactless card, there was a problem in that it was read unnecessarily without touching the card reader.

Thus, in order to overcome this problem, the chip embedded in the card and the LED can be directly connected to the card reader to switch the power to the power provided by the card reader, thereby turning on the LED. There was a problem that the LED is not turned on.

In addition, the loop coil is formed near the chip, and the loop coil is formed near the LED, and when the power is supplied to the chip, the switching may be performed to supply the power to the LED, but if either of the two is disconnected, There was a problem that the LED can not be turned on.

The present invention has been made to solve the above problems, the purpose of which is the induced electromotive force from the card reader to the loop coil only when the user presses the switching button provided on the inlay sheet between the upper card and the lower card whenever the card is used. The present invention provides a switching access card that enables the LED to emit light while the card is read to indicate the use of the card.

In addition, another object of the present invention is that when the user touches the card reader to the card reader while pressing the switching button or touches the card without contact, the LED can be emitted while the card is read and the card processing status of the voice can be output under the control of the microchip. To provide a switching access card.

In addition, another object of the present invention is to provide a switching access card that allows the user to press the switching button while holding the card to the card reader to display the card processing status on the screen under the control of the microchip while reading the card. It is.
