| 20120066443 | READING/WRITING CONTROL METHOD AND SYSTEM FOR NONVOLATILE MEMORY STORAGE DEVICE - The present invention is adapted to data storage technology field, and provides a reading/writing control method and system for nonvolatile memory, the method including the following steps: dividing valid blocks in the nonvolatile memory into different zones, the zones including at least one data zone having fixed number of valid blocks and one exchange zone having at least two valid blocks; creating a mapping table of logic blocks and physical blocks in each zone; establishing a mapping table of logic pages and physical pages in the blocks based on redundant area information of pages in the blocks, and storing the mapping table of the logic blocks and physical blocks in each zone and the mapping table of logic pages and physical pages in each block in a private data area; and writing data segments in an idle page of the blocks of the data zones in sequence, or reading data segments from valid pages in the data zones, thus the data reading/writing speed and efficiency is promoted. | 03-15-2012 |
| 20100163619 | CARD READER AND MOBILE PAYMENT TERMINAL - The present invention discloses a card reader and a mobile payment terminal. The card reader comprises an MCU which is connected to a single interface smart stage card and is configured to read data from the single interface smart stage card or write data in the single interface smart stage card; an NFC antenna which is connected to the MCU and is configured for performing data interchange between a contactless card reading terminal and the single interface smart stage card; and a DIU which is connected to the MCU and is configured to realize communication between the MCU and a communication terminal. In this way, by installing an NFC antenna, the single interface smart stage card in the card reader can interchange data with a contactless card reading terminal wirelessly without connecting to the DIU. | 07-01-2010 |
| 20100163618 | TRANSACTION METHOD WITH E-PAYMENT CARD AND E-PAYMENT CARD - The present invention discloses a transaction method with an E-payment Card and an E-payment card. The method includes the steps of: receiving transaction instructions sent from a peripheral e-equipment using communication interfaces of an E-payment card; authenticating the peripheral e-equipment's authorization of access to a storage unit of the E-payment card using a processor of the E-payment card; and if the authentication is successful, performing corresponding operation to the data in the storage unit in response to the transaction instruction by the processor of the E-payment card. The E-payment card is provided with a plurality of communication interfaces, through which it transacts with different peripheral e-equipments to be suitable for the transactions, charging, etc. in different occasions, which is more convenient for users. | 07-01-2010 |
| 20100163614 | CARD READER AND MOBILE PAYMENT TERMINAL - The present invention discloses a card reader and a mobile payment terminal. The card reader comprises an NFC antenna connected to a dual interface smart stage card card for performing data interchange between a contactless card reading terminal and the dual interface smart stage card card; an MCU connected to the dual interface smart stage card card for reading data from the dual interface smart stage card card or writing data in the dual interface smart stage card card; and a data interface unit connected to the MCU for establishing communication between the MCU and a communication terminal. In an embodiment of the present invention, by installing an NFC antenna, the dual interface smart stage card card in the card reader can interchange data with a contactless card reading terminal wirelessly in a passive environment. | 07-01-2010 |
| 20080215881 | Method Of Encrypting/Decrypting The Document And A Safety Management Storage Device And System Method Of Its Safety Management - A method of encrypting/decrypting the document and a safety management storage device and system method of its safety management, using for the safety management of electronic documents, the said system comprising a PC or mainframe installed with common reading software and a storage device of safety management connected to the said PC/mainframe through hot-plug; when connected to the mainframe, the said storage device is enumerated as a USB CDROM device at least. The user owns the said storage device can encrypt the electronic documents by using the encryption keys to generate an encrypted document with the same file type, also can open the encrypted document by using common reading software, and then use the document according to the predetermined operation authority. By using present invention, the users and the range of using the documents will be limited through the control of the distribution of the said storage devices, thus, a document safety management system with high security and easy-use will be established, and with the advantage of easy control, low cost of investment and maintenance. | 09-04-2008 |
