The invention is a syringe needle Protection Cover, including a Needle Hub to secure the needle base and a side-opening cover with an Axial Slot to protect the needle. The needle is at the center of the needle base, and a Longitudinal Member forms a side-opening cover that integrates with the Needle Hub at one side via a Hinge. The Longitudinal Member opens easily and locks closed securely. When the Protection Cover is in the closed position, it is difficult to force open, thus making it difficult to reuse a needle. The protection cover gives users more than one visual indication that a needle has been used, locks in a closed position with multiple locking structures, and after use, deforms the needle so as to render it non-reusable.

A method for realizing magnetic stripe card transaction by means of IC card is used to read data from IC card or to complete transaction between a terminal integrated with IC card read capacity and a transaction processing system. The method includes the following steps: (1) a cipher key file which stores cipher key information is set in an IC card for use only and can not be read out; (2) during each transaction, the IC card generates a dynamic process cipher key according to a preset method and returns the sensitive information containing magnetic stripe information and encrypted by the process cipher key to a terminal; (3) the terminal organizes transaction request message and transmits the message to a transaction processing subsystem; (4) after receiving the transaction request message, the transaction processing subsystem completes decipherment and processing of the magnetic stripe information and returns transaction processing result to the terminal. With the invention, the magnetic stripe information read out from the IC card every time is encrypted by different process cipher keys; moreover, the invention sets a series of data demands and security mechanisms stored in the IC card, thereby ensuring data storage safety of the IC card and reducing the possibility of data leakage.
