Because the card meter the existence of various risks such as bayonet or the sensor (reader) vulnerable, the card is not easy keeping, easy to damp circuit boards, etc., and key-press code type prepayment meter pioneered prepayment code control technology, users can Easy and convenient way to purchase a variety of resources (electricity, water, gas), greatly reducing operator management and operational costs. Key-press code Meter installed the security module encryption algorithms inside, so that the code meter has a very high security. With long service life, anti-jamming and anti-attack capability, and wide voltage and wide temperature operating range and other characteristics can be achieved electricity, water, gas to be charged together, as well as is electricity, water, gas best choice of charging methods, monitoring methods and management.
