The CA568-K prepaid water meter is designed with the growing market demand in mind, particularly in Africa, where prepaid systems are gaining popularity. This trend is driven by the need to minimize non-revenue water and ensure quicker returns on investment. Prepaid systems also eliminate concerns over unpaid bills, offering a more efficient and secure solution for water utilities.
From a technical standpoint, the CA568-K operates in full compliance with the STS (Standard Transfer Specification) encryption standards. It requires users to enter a unique 20-digit token that includes various data such as the meter ID and recharge amount. Each token is valid only once per meter, ensuring the security of transactions.
In terms of protection against tampering, the CA568-K is equipped with multiple safeguards. Any attempts to tamper with the meter—such as using magnets, damaging the device, or removing the battery—trigger its protective mode, automatically shutting the system down. Restoration can only be done by an authorized technician, ensuring that unauthorized tampering cannot go unnoticed.
Moreover, the CA568-K’s token-based system supports seamless integration with mobile payment platforms and third-party payment solutions. Since it does not rely on physical cards, the vending process is encrypted and can be conducted wirelessly, streamlining revenue collection and enhancing cash flow management.
To ensure smooth integration with existing systems, Calin provides a comprehensive set of APIs, offering enhanced mobility and functionality for users and utilities alike.
