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 erasable 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 fuel dispenser 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. Staff card Hold by general staff of filling stati fuel dispenser fuel dispenser

la s Luanda comes second and Congo s Kinshasa fifth, just behind Oslo and Moscow. Even Gabon s Libreville is deemed more expensive than Tokyo. Why are cities in some of the world s poorest countries also the priciest? In Harare, record-breaking inflation, shortages of basic goods and an overvalued official exchange rate all keep prices translated into foreign currency dizzyingly high. In restaurants, glossy menus no longer carry prices, which get printed separately with inflation at almost 1,100% a year, the cost of meals changes too fast. Toothpaste, at $8 a tube in Harare, is almost three times more than in New York and e fuel dispenser ight times more than in Johannesburg. The price controls that the government is slapping on a lengthening list of goods and services are likelier to boost the black market than cut inflation to tolerable levels. Alas, last month s Zimbabwean budget gave little evidence of serious reform, so money will probably continue to be printed willy-nilly. Expensive inconveniences for expatriates mean life or death for millions of wretched Zimbabweans. In Luanda, on the other hand, the economy is booming and inflation a mere 12%. But after decades of war, not much is produced at home, bar oil and diamonds, so most things are imported and command high prices. Supermarkets are few. Foreigners tend to eat at just a handful of restaurants where their digestive systems may not suffer and where dinner for two costs $150-plus, making even London look cheap. Foreigners with a sweet tooth may feel sour in Kinshasa, where a kilo of sugar costs twice as much as in New York. Expatriates feeling ripped off in Angola, Zimbabwe or Congo need not despair they can move to the kingdom of Lesotho, whose capital, Maseru, is rated in the survey as the cheapest place on earth—for foreigners. © 2006 .  About sponsorship French foreign policy The glory days are passing Dec 13th 2006 | PARIS From The Economist prin fuel dispenser fuel dispenser
