Description

Priority Card {Priority Card}

The present invention relates to a priority card having priority over a card reader, wherein a specific priority is given among a plurality of contactless cards existing in an operating field of a card reader in a step of manufacturing a contactless card at a card making institution. By blocking the RF field for contactless cards other than the contactless card, the contactless card terminal preferentially processes only the specific contactless card to which priority has been given.

A contactless card is a type of card that supplies power or exchanges signals without using a current-generating element (contact) .It is a close type and a remote type depending on the approach distance between a contactless card and a card reader. Remote Coupling) is divided into Proximity, Vicinity and Microwave (Radio Frequency).

Such a contactless card does not need to be inserted into a card reader and does not require accurate card positioning, so it is easy to design and manufacture, and the terminal can be manufactured ruggedly and inexpensively, thereby reducing maintenance costs and allowing the card itself to be machined. It does not have any contact surface, so it can be used for a long time because it is strong against static electricity, chemical damage, moisture, contamination, dust, or friction, etc., and it is difficult to interpret contents because it is impossible to directly access the card. .

Due to the features and advantages of such contactless cards, a number of card issuers and / or card making organizations issue and / or manufacture various types of contactless cards, and card users may respond to at least one or more of the same card readers. You can carry a contactless card.

1 is a simple diagram of the configuration of a general contactless card.

A contactless card consists of at least one chip that reacts to a card reader and at least one antenna that powers or handles signal exchange with the chip, the chip and antenna being enclosed within an insulating material such as plastic.

Insulating materials provide electrical characteristics that allow the antenna of a contactless card to respond to the card reader and power or exchange signals with the chip of the contactless card through capacitive coupling and / or inductive coupling. do.

Meanwhile, the card user may carry at least one card with a contactless card as shown in FIG. 1 through a wallet equipped with a card alignment frame as shown in FIG. 2, wherein the contactless card within the operating range of the card reader It may be physically arranged as shown in FIG. That is, referring to FIGS. 2 and 3, at least one contactless card such as FIG. 1 responsive to the same card reader may physically overlap and exist within the operating range of the card reader. The card reader then preferentially processes the contactless card that preferentially reacts among the plurality of contactless cards within its operating range, wherein the contactless card that preferentially reacts is non-selective.

Of course, the existing contactless card processing method using the existing contactless card as shown in FIG. 1 is a big problem and / or inconvenience in contactless card processing, in addition to the problem that the card user does not have the right to select a contactless card when processing is completed in one reading. The ham may not occur. For example, in the case of a transportation card for a bus, processing can be completed with only one reading in the step of getting on. At this time, the card user cannot select a card to be read, but no processing error may occur in the card reading itself.

However, when the processing is completed in two readings, not only the card user's right to select a contactless card is guaranteed, but also inconvenience in processing the contactless card occurs. For example, in the case of a subway traffic card, the processing of the contactless card is completed by reading the contactless card once at the entrance and reading the same contactless card at the exit. At this time, in the existing contactless card system using the contactless card as shown in FIG. 1, which is not given priority, it is not guaranteed that the contactless card read at the entrance can be read at the exit. In this case, the card user has the inconvenience of having to selectively read the contactless card at the entrance of the wallet as shown in FIG. 2 for safe contactless card reading, and repeat the above process at the exit.

An object of the present invention to solve the above problems is to produce a non-contact electrically conductive material (conductive plate and / or net) and the antenna of the chip and / or antenna of the contactless card in the step of manufacturing the contactless card in the card manufacturing institution and the antenna By nesting in parallel, the conductive field of the plurality of contactless cards present in the operating field of the card reader blocks the RF field for other contactless cards present in the rear of the contactless card containing the conductive material. The present invention provides a priority card that gives priority to a contactless card containing a substance.
