RAM: to store data in the form of files for processing by a computer's central processing unit (CPU). Once power cut, data in RAM will be lost. Capacity is 256 byte to 1k. EEPROM: electrically erasa fuel dispenser ble programmable read-only memory, used for storing customer’s data. From view of structure, filing IC card actually is a full-mounted singlechip (SCM). Filing IC card security Since storing large information needed to protect, filling IC card has to have high security, not only preventing inappropriate operation, but also restraining illegal visit and manipulation. Therefore, effective protection mechanism is considered in design and manufacture so as to be provided with high capacity of defending attack. The major safety measures of chip are: chip identifying code, preventing disassembly and erasion, data encryption, etc. Chip identifying code: each chip has a unique identifying code, called “chip serial number� Chip preventing disassembly: photoconductive and pressure sensitive components check exterior mechanical force on chip. Once open seal all sensitive data will be cleaned. Chip anti-detect: in order to prevent illegal detect of data, adopting high/low voltage inductive sensor, low frequency inductor and anti-interference technology. Anti-erasion: adopting effective measures to prevent erasing memory through ultraviolet, x-rays and like on. Data encryption: operation system stored in ROM is core of CPU card, which adopt code encryption and special technology hiding ROM area. Meanwhile, encrypted inductor is able to quickly erase RAM area so as protect temporary data and encrypted lock. As for EEPROM area, it is adopted specially safety protection measures in chip production. IC card categories and purpose Customer card This kind of IC card is hold by vehicle driver or customer. Customers need to enter personal identification number (PIN) into keyboard as filling. Filling card includes general customer card and unit card.

return is unwelcome. Bob Crow, the ex-Communist leader of the RMT, is a man cast in the old mould. A fan of Arthur Scargill, the fire-breathing leader of the miners whose great strike, broken by Marg fuel dispenser aret Thatcher in 1985, marked the end of union might, he makes no secret of his impatience with the conciliatory tone adopted by many unions thereafter. His union has threatened to strike for all sorts of reasons, from worries about safety after the July 7th bombings to support for a colleague who was sacked for playing squash while off work with an ankle injury. Strikes have been threatened on each of the past three New Year s Eves. Such hardline tactics are both worrying and effective. The Tube carries 3m people a day and it is well within the unions power to disrupt the capital. Most strike threats remain mere threats, but even hints of disorder have borne fruit. London s bus drivers, who work in a competitive market where unions have less power, earn up to £25,000 ($44,000), including overtime. Tube drivers, by contrast, make £35,000 a year and get up to 43 days holiday. Station staff earn £21,000—slightly less than the national median—but, thanks to generous leave arrangements, work far fewer hours than most. At a time of generally falling union membership, the RMT is one of the fastest- growing in the land. London Underground has said that it will stick to its guns. Given the power that the union wields, it will be impressive if managers win the fight over work rosters. One thing only seems certain more misery for the passengers who pay for it all.  © 2006 . Failing schools Off with their heads Jan 12th 2006 From The Economist print edition How to improve school performance ALL the prattle about school choice, beloved of New Labour and Tories alike, is meaningless to a child who ends up with no choice but to attend a failing school. And although failing schools are less numerous than they once were, there are still a lot of them around 1,557, according to the fuel dispenser fuel dispenser
