Description
CONTACTLESS ELECTRONIC CARD
Technical Field
The present invention relates generally to a contactless electronic card, and particularly to a contactless electronic card with a built-in contactless radio frequency electronic chip, which is provided with a ferrite core for canceling interference from electromagnetic waves and a magnetic field, thereby allowing the electronic card to be used while being attached to or enclosed in a portable item or terminal containing an interfering material.
Background Art
Currently, with the rapid growth of the information society based upon credit, card users, such as people and corporations, deeply feel the risk and inconvenience in handling cash. Government authorities promote using cards in business as an economic policy. Therefore, use of various cards in business is rapidly growing. Examples of conventional cards include various types, from a simple recording medium having a magnetic stripe placed on the backside to record user i identification information, up to an Integrated Circuit (IC) card having a built-in
Radio Frequency Identification (RFID) electronic chip.
A RFID card 1 having a built-in chip is divided into a contact type card or contactless RFID card. The contactless RFID card 1 is being used as a security card key for regulating entrance and exit, or as a petty-settlement means for paying a small amount of money such as a subway or bus fare. Inside the contactless RFID card 1, there is a loop antenna and RFID electronic chip to communicate with a card reader 2 installed in a specific place. The card reader 2 is adapted to read identification information and purchase information registered in the electronic chip and transmit them to a financial server 4 or security system via communication means 3.
In the RFID card 1 used as a petty-settlement means, a user is primarily provided with a service, and, thereafter, purchase information about the provided service and the unique identification information of the electronic chip enclosed in the RFID card 1 are transmitted to the financial server 4 immediately, or later and manually. At a due date after a certain period of time, the service is paid for as a deferred payment.
Also, the RFID card 1 can be used as a rechargeable card to pay fares for public transportation. The rechargeable RFID card 1 pays the fares by means of charged money information while communicating with the card reader 2, and then stores new settled money information. Thereafter, the user pays a certain amount of money at a charging station having a charging apparatus, and then charges the RFID card 1 with the amount of money, thereby storing new money information in the RFID card 1.
According to the conventional contactless RFID card 1 described above, however, the user separately carries the card, resulting in inconvenience and the risk of loss. Additionally, for the rechargeable RFID card, the user should personally visit the charging station to charge the card with a certain amount of money.
Currently, a security card key and a RFID card for petty-settlement, which are used in a contactless manner in conjunction with the card reader, are generally used while being isolated from interfering materials and thus do not experience interference from electromagnetic waves and a magnetic field. Therefore, electric energy can be transmitted to the electronic chip without any damage or loss.
However, when the RFID card is maintained in a purse or bag containing an interfering material, such as an iron core or a metal piece and they are read by the card reader, user identification information recorded in the RFID card cannot be read due to interference by the interfering material. Additionally, when the loop antenna enclosed in the RFID card is damaged due to cutting or breakage of the RFID card, it is impossible to read the RFID card. A service, which is provided through the RFID card combined with the portable terminal, is lately under discussion. However, there is a serious
technical problem in reading user identification information due to interference by the interfering materials of the portable terminal including an iron sheet, a circuit, and sheet metals for shielding electromagnetic waves and EMI.
Disclosure of the Invention
Accordingly, the present invention has been made keeping in mind the problems as set forth above, and it is an object of the present invention to provide a contactless electronic card with a ferrite core for canceling interference from electromagnetic waves and a magnetic field, which allows the electronic card to be used while being attached to a portable item such as a portable terminal. Another object of the present invention is to provide a contactless electronic card with a ferrite core for canceling interference from electromagnetic waves and a magnetic field, which allows the electronic card- to be used while being disposed between the nonmetallic material constituting the contour of the portable terminal or portable item and the EMI shielding material or device applied to or mounted on the nonmetallic material.
In order to accomplish the above object, the present invention provides a contactless electronic card attachable to a certain position of a portable item or portable terminal, comprising: a loop antenna for communicating with a card reader; an electronic chip for transmitting user identification information stored therein at the request of the card reader; and a ferrite core for canceling interference from electromagnetic waves and a magnetic field while the card is read by the card reader.
In addition, the present invention provide a contactless electronic card interposed between a nonmetallic material constituting the contour of a portable item or portable terminal and an electromagnetic interference (EMI) shielding material or device applied to or mounted on the inner face of the nonmetallic material, comprising: a loop antenna for communicating with a card reader; an electronic chip for transmitting user identification information stored therein at the request of the card reader; and a ferrite core for canceling interference from
electromagnetic waves and a magnetic field while the card is read by the card reader.
