SZD42-B Transmission Disk
Introduction:

The transmission 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 transmission disk is an electronic device that enables safe data transmission between the invoice tax control disk and management software with the help of invoice software.
