  • Publication number: 20070084933
    Abstract: The present invention relates to an information card with multiple storage media. Combining reading and writing characteristics of magnetic strip storages, ICs, PFIDs, and etc. with large storage capacity of a compound printing 2D barcode, the invention uses a base card with a magnetic strip storage medium or a base card beset with an IC read-write chip, and a RF read-write chip. On said base card contains a first 2D barcode which has difference reflectivities to lights in the first spectrum area between bars and spaces, there is a designated relation between data stored in the magnetic strip or the IC chip, RF chip and data stored in the first 2D barcode. The invention discloses a read-write device of the information card comprising a Contact Image Sensor (CIS), a magnetic head or an IC chip reader, an RF chip reader. The invention further discloses a method for reading and writing data in said information card.

  • Patent number: 7175091
    Abstract: An insert-type barcode reader has a body support with an insertion slot for receiving a card with barcode. A circuit board and a CIS component module electrically connected to the circuit board with each mounted to the body support to scan and process signals. A roller is mounted to the body support for movement relative to the CIS component module to allow the card to be properly guided into the insertion slot and tightly pressed onto the CIS component for accurate scanning of the barcode on the card. Two photoelectric sensors mounted to the body support are electrically connected to the circuit board for sensing the card entering and leaving the insertion slot to control starting, running and stopping of the scanning function of the CIS component module.
