Description

technical field [0001] The invention relates to a prepayment system device, in particular to a prepayment system device for water, electricity and gas. Background technique [0002] The previous IC card or magnetic card prepayment system devices used for water, electricity and gas are generally composed of issuing card system devices and metering control system devices. ), the consumption amount is stored in the card, and the user reads the amount into the metering control system device for system use by inserting the card. During this process, the user and his card are necessary for connecting the issuing card system device and the metering control system device indispensable link. The use of such a prepaid system device requires the production and sale of cards, and the cards have disadvantages such as loss and wear during use, and it is difficult to control and intervene in the working state of the user. Contents of the invention [0003] The purpose of the present in...
