Non-contact ic card and card reader that can be suspended to read and write

Abstract

Non-contact IC card and card reader that can be suspended to read and write. The IC card includes PVC sheets, induction antennas and chips. The PVC sheets include upper and lower circuit printing layers, middle layers and outer coating layers. The middle layer is on the upper and between the lower circuit printing layers, the middle layer is provided with a magnet accommodating groove, and a permanent magnet is arranged in the magnet accommodating groove. The card reader includes a housing, a card reading circuit module, a permanent magnet of the card reader, an electromagnet control circuit and a power supply. The direction control electromagnet group includes at least four groups of electromagnets distributed at intervals. The center of the direction control electromagnet group is connected to the card reader. The center of the permanent magnet of the device coincides; the electromagnet control circuit is provided with a 4-bit sequential drive circuit, a drive power supply circuit and a clock circuit electrically connected to each other, and the coil on the electromagnet is electrically connected with the 4-bit sequential drive circuit. In the present invention, an intermediate layer embedded with permanent magnets is arranged in the IC card, and a permanent magnet and a direction control electromagnet group are arranged on the card reader, so that the IC card can be suspended above the card reader to read and write information.

Description

technical field [0001] The invention belongs to the technical field of non-contact IC cards, and more specifically relates to a non-contact IC card which can be suspended above a card reader for reading and writing information and a card reader matched with the card. Background technique [0002] With the continuous development of smart card technology in recent years, IC smart cards have been widely used in finance, medical care, public transportation, security systems, telephone communications, social security and other fields, and the appearance of cards is also ever-changing. Existing IC cards are mainly classified into two types: contact type IC cards that can write and read information by contact with a dedicated device, and non-contact IC cards that can write and read information only by approaching a dedicated device. [0003] RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identif...

AI Technical Summary

Problems solved by technology

Although the existing non-contact IC card can read and write operations without contacting the reading and writing equipment, it still needs to be held or placed on the reading and writing equipment, and there is no IC card that can be suspended above the reading and writing equipment by itself. Designed an IC card that can be read and written in suspension. As long as the card is placed on the card reader, you can let go of your hand. The card is suspended in the air to complete the card reading and writing process, making the card reading operation easier
