Comparison of Contact less IC Card and Contact IC Card Gas Meter Description Damp Proof Security Anti-Attack, Anti-Stealing Gas Valve Convenience Contact less IC Card Prepaid Gas Meter There is no any exposed electrode, and the circuits are completely sealed, so it has good damp proof function. Wireless data exchange, so the security is very high. No exposed electrode. So cannot be attacked by external strong current. Explosion prevention of electric valve, no locked-rotor, low power consumption quick speed of open and close valve, long serviced life. No direction limitation, no contact point, wireless data transmit, convenient for using. Contact IC Card Prepaid Gas Meter There is exposed electrode, and the circuits cannot be completed sealed, so the function of damp proof is not so good. In moist environment, there will be wrong data with the IC card; and after long time using, the contact point will rust, and erode. Wire data exchange, so the security is not so good. Use external electric field( for example lighter, 220V voltage) to attack the exposed electrode, and will make the system easily paralyzed, while there is no any vestige, so it is easy for customer to steal gas power. Electromagnetic Valve: knocking the pipe can open the valve. Has direction limitation, and contact point, so will be poor contact, wrong data transmission, not so convenient for using. DIEMENSION:

OVERVIEW: Smart Prepaid System Contactless IC Card gas meter is suitable for measuring the flow of natural gas, coal gas and liquid gas. One household fixed one meter and consumer uses gas by IC card. No need to charge house by house and avoid owing. Customer goes to gas administrative department and prepays for power firstly, then staff will give customer an IC card, input purchased power into the IC card through software and IC card reader-writer. Then customer takes his IC card to home and swipes it on the induction area of gas meter and then the purchased power will be automatically put into his meter. After gas meter receives the data of purchased power, it will switch on and supply gas power. During the using period, the microcomputer inside the gas meter will automatically subtract the gas power and when the purchased power has been used up, the gas meter will automatically close valve and stop gas power supply. At this moment, the customer has to purchase power again for using next time. With support of software and IC card reader-writer, gas administrative department can supervise total used gas, total purchased gas and so on. High efficiency, no need of house call fee-charge and avoid owing. SYSTEM COMPOSITION: The system consists of four parts: smart gas meter, contactless IC card, IC card reader-writer and software. 1: PRE-PAID GAS METER 2: CONTACTLESS IC CARD (WATER PROOF) 3: IC CARD READER-WRITER MRW MRW-S 4: SMART MANAGEMENT SOFTWARE Smart Management Software has friendly interface and is easy to learn and operate. It can support all smart prepaid meters. With many functions, like create file, open account, deal with daily business, sale inquiry, multi inquiry, report summary, read/write card, input/collect data, print bill and check blacklist, etc.
CHARACTERISTICS: o Managing all the Gas meters, smart and strong. o Creating files of different meters. o Convenience for operator to open account, recharge, reissue card, cancel account, replace meter, etc. o Collecting consumption records stored by IC card reader-writer and then upload to computer for backup. o Inquiring sale records by daily and monthly or inquiry for any period of time. o Summing up total purchased amount and money of different sale regions, meters or times. o Automatically backup or recover data.
