Smart Card STS Prepaid Water Meter

LAISON Smart Card STS Prepaid Water Meter is an innovative water meter developed by LAISON, which conforms to STS protocol and supports data transmission of RF Card. This prepaid meter can support both keyboard 20-bit code recharge and RF card (customer card) recharge. Bidirectional data exchange between meter and prepaid system is realized by Philip S70 non-contact card , which makes up for the deficiency of one-way communication in STS protocol. Then it's convenient for water companies to manage users' information by reading back basic meter information such as total consumpted water, remaining water, total purchased water, ect.
