authorized command and startup pump without operator interference. Non-auto authorized filling: the send of authorized command to switch on pump needs operator’s help after holding up nozzle. Additional requirements Aside from the function ‘card-control�? it should abide by the requirement of ‘card-linkage�? that is, no operation without card. ‘Card�?means filing card (CPU card). IC card fuel dispenser would be resting state in which any filing operation related conducted if no valid card is inserted. As insert valid filing card and pass two-way attestation, IC card fuel dispenser can be operated including setting and filing. The balance of IC card is checked in filling process. If don’t meet requirement fuel dispenser would be stopped. Once IC card is pulled out in filling process, IC card fuel dispenser would come to halt immediately, transaction record would be stored in IC card system. The card, only finish previous payment of deduction can become a valid card to next filling. Realization modes Two-way attestation between filling card and IC card termin fuel dispenser al Filing card is CPU card, containing password that match fuel dispenser. Password system includes these operating passwords used for payment deduction, setting grey card and password attestation. IC control unit of fuel dispenser contains password carrier processed encryption function. IC card system control to fuel dispenser The filling operation of fuel dispenser should be controlled by IC card system; IC card system has supervision function to filing process; control the open and close of pump or solenoid valve; control replacing op fuel dispenser erati fuel dispenser on such as unit price, product, etc. 5.3 Basic function of card- controlled fuel dispenser The following items are the basic functions: Card-linkage (card-controlled filling) Starting operation needs to insert IC card; If take out IC card, filing operation will be stopped Multiple filling types Having three kinds of filling types: presetting volume or money to fill oil, filling

s traditionally greet Colombia s new presidents with violence. So a series of recent attacks, the bloodiest of which was an ambush on July 31st of an army patrol, probably by the FARC, the country s main rebel group, came as no surprise. The only novelty is that, for the first time in modern history, the outgoing and incoming presidents are the same man, Álvaro Uribe, who will start a second four-year term on August 7th. In his first term Mr Uribe s strategy of “democratic security�?sharply reduced the number of massacres, murders and kidnappings that had plagued the country, which is why he won 62% of the vote in the election on May 28th. Yet some, mostly rural, parts of Colombia remain unsafe, and critics say the government is insufficiently democratic in security matters. Mr Uribe will find his second term harder than his first. He owes his military success in part to $600m a year of aid from the United States, which helped finance a one-third increase in the size of the armed forces and the police; it also pays for schemes to eradicate coca, from whic fuel dispenser h cocaine is produced. Even so, the government s forces are too stretched, says Sergio Jaramillo, a security analyst. Many of the new Stretched thin, but paying recruits have simply replaced some of the 30,000 right-wing court to Uribe paramilitaries who laid down their arms in April in exchange for leniency for past crimes. To pacify the country, says Mr Jaramillo, the government will have to extend the rule of law and the benefits of economic g fuel dispenser rowth fuel dispenser , which has averaged around 5% a year recently, to areas that have been controlled by the FARC and the paramilitaries. This will not be easy. The paramilitaries have largely stopped their killings since their demobilisation, but they continue to threaten investigators and others, to traffic in drugs and to profit from stolen property. In a letter to Mr Uribe on the eve of his inauguration, Hu
