How to charge for Delixi prepaid electricity sales management system

This system can write the meter number on the card through the card reader, including the last purchase of electricity, the number of purchases of electricity, the current purchase of electricity, the used electricity and the remaining electricity of the meter, and then find the R&D personnel of the manufacturer or people who have worked before to make a decrypted property matching system for you to recharge directly. For example, your property card number is 123456, the last time you purchased electricity was 12 degrees, and the number of times you purchased electricity was 1 time. The electricity meter has used 10 degrees, and there are 2 degrees left. R&D personnel can directly read this information through the card, and then directly recharge the card in the new system through the matching new system! Then the data accepted by the meter is generated in the card, and then it can be recharged directly! !
