od is to add some message at start or end of information, the additional information is authentication code that generated from calculation of message command. Authentication code correlate to message contents and used to verify accuracy if message. MAC has 4 byte length. Firstly, message is decoded after reception; then, decode authentication code by prescribed calculating mode. Thirdly, compare the two authentication code, if they are same, message has not been modified during transmission; if different, they have been modified. Chapter IV Station’s safety and environmental protection Article I Lightningproof The design and construction of filling station for vehicle should comply with the following requirements: The ligntningproof point of tank at least has two with resistance less than 10Ω. It is very important to steel tank for reducing ligntning potential and step voltage. The number of grounding point and earthing resistance are regulated based upon domestic regulation and 20 years practice. As for ground steel tank with fire-resistance need not install lightning conductor because its continuous electric capacity. Horizontal tank generally has more than 4mm steel board, processing lightning protection function as long as making earth fuel dispenser ing. Therefore, it could need to install lightning conductor. All metal parts of tank body, indicating window and fire-resistance device of buried tank should grounding connection, resistance not exceeding 10. The reason for doing that is to provide a passage for direct lightning and lightning induction, preventing serious damage. fuel dispenser Ground tank storing flammable oil could only make lightning grounding. As vap fuel dispenser or density of ground tank is lower and ignite point is high, lightning not easily to ignite oil in short time, this kind of tank just need the lightning grounding. However, the near construction and building should be calculated in terms of distance of anti-lightning. Station building and awning should adopt lightning belt to prevent strike. Lightnin

€€ã€€ CardPreAuthorisationLoyaltySwipe Response　　 CardPreAuthorisationLoyaltySwipe Request　　7.10 POS EPS XML Interface　　The following examples are only a possible implementation exemplification.　　CardPreAuthorizationLoyaltySwipe Request　　This message will be used to trigger a PreAuthorization process in the EPS Server solution. The POS system sends　　it after startup and the EPS Server waits till the customer has inserted a card or the timer expired (timer value = for　　example 5 minutes). In case of timer expiry the EPS Server sends a CardPreAuthorization response with　　OverallResult = TimedOut. The POS starts again a CardPreAuthorization.　　The customer has two possiblities:　　 insert a loyalty card first and then a payment card or　　 insert immediately the payment card.　　In the first case the EPS Server sends the loyalty card data (PAN) to the POS within CardPreAuthLoySwipe-　　response message. In the second case the POS sends a separate LoyaltySwipe Request to trigger the Loyalty card　　reading.　　After the customer has inserted a payment card the EPS Server will inform the POS system via the Device request　　with RequestType Event that a customer has inserted fuel dispenser a payment card. Before the POS receives this request it is　　possible to abort the PreAuthorization request and the EPS will send a CardPreAuthorization response with　　OverallResult = Aborted. If the customer change the default language on the dispenser or vending machine it sends　　an AbortRequest message to the EPS server an fuel dispenser d after a successful abort it sends a new CardPreAuthorization with　　the corre fuel dispenser ct language code.　　The table describes the XML message layout and the parameter description. It also describes if the parameter is　　mandatory or optional.　　XML Parameter Presence Description　　RequestType M CardPreAuthorizationLoyaltySwipe　　Wor
