IZSL - (15B-25B)CPU card intelligent cold water meterProduct Introduction:
CPU card water meter is a summary of our company's current situationICCard smart water meterIt is a new generation of intelligent products successfully developed based on its application experience and prediction of the future market development trend. The water meter uses the CPU card as the media for information storage and transmission, and completes other authentication with the ESAM module in the meter. The file structure and operating system of the intelligent CPU card comply with the specification of the People's Bank of China's financial IC card (PBOC specification), which can easily realize the application of one card with other applications, and can also easily realize the application of one card and multiple meters with the charging management platform. This product complies with industry standards CJ/T133-2007 and GB/T778-2007.

CPU card intelligent cold water meterFunction Introduction:
◎ Sex: The CPU card adopts a key management mechanism, and the authentication process is dynamically carried out through encryption algorithm calculations, with a low possibility of being decrypted and attacked in practical applications; After installing the SAM module in the table, the mutual authentication between the IC card and the SAM module is independent of the microcontroller in the IC card table. This breaks through the huge loophole of storage card and logic encryption card key control in the meter factory. The key of the CPU card water meter is controlled by the water company through two or more inputs, and is then authenticated by departments such as the Commercial and Information Commission and the Ministry of Construction, thus protecting the entire process of card transactions.
Compatibility: CPU card+ESAM enables different manufacturers' watches to be unified on one platform, and the card can be used interchangeably among different watch manufacturers' watches, solving the problem of incompatibility between storage cards and logical encryption cards, and eliminating the need for water users to use each oneMagnetic card water meterThe trouble of having to use an additional system.
◎CPU card intelligent cold water meterScalability: The CPU card stores data in a file format and manages it with a key, making it easy to implement a multi-purpose solution for one card, achieving universal use of water, electricity, and other meters.
◎ Standardization: The COS operating system of CPU cards generally meets the financial card specifications. This can easily achieve bank networking fees.
