## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a safety cover design for financial transaction device, and more particularly to the integrated circuits card reader having safety cover design for preventing penetrating, exploiting and manipulating to protect the information stored in financial transaction device from illegal accessing.
2. Description of Related Art
Integrated circuit card also well-known as smart card, is being used widely today to meet the convenient of the information exchange provided by electrical system. Integrated circuit card has various types practiced in many fields. Bank card or credit card can be used in financial transaction. ID card can be used for confirming individual identity. Other fields like travel, communication, and medical system are also involved integrated circuit card implementation. Integrated circuit card can store amount of individual information, and access conveniently based transaction discrepancies.
The individual information stored in the integrated circuit card is access during certain transaction including cash withdraw, money transfer, consumer credit, cumulative dividend and micropayment. Several types of integrated circuit card are recognized in different payment. Bank card used for cash withdraw and money transfer has magnetic stripe formed on surface. Metro card mostly completes payment through wireless. Combo card combines with magnetic stripe and wireless unit, and being used in variety payment with security code. Integrated circuit card has been used in many transaction rather than cash, and common current payment of the majority. However, the convenient and widely used in common life brought by integrated circuit card, also increase stealing risk of personal credit information exposed during transaction.
