SZD42-A Tax Control Disk
Introduction:

The tax control disk is a tax control management device designed to meet the demand of the transport industry for tax management (including the deduction function). With years of experience in developing tax control IC cards, Hengbao participates in the design of tax control disks and transmission disks. Hengbao's tax control disks and transmission disks are both in line with the Technical Specifications for Invoice Tax Control Disks and Transmission Disks, and support the tax control algorithm and asymmetric RSA algorithm. Highly reliable, safe and flexible, they can be widely applied in the transport industry (with the deduction function).
The tax control disk is an electronic device that offers invoice tax control functions with the help of invoice software. It meets the requirements of tax authorities on invoice management, and ensures invoice tax control data to be generated correctly, stored reliably and free from falsification.
