The SDC (Sales Data Controller) may be an accredited electronic device or a software (E-SDC) purchased by the taxpayer and authenticated by the independent secure element (SE), or a virtual (V-SDC) provided by the TA, and accessed over the internet using digital certificate. Whether E-SCD or V-SDC, the purpose of SDC is to enable connection to the TA TaxCore server. The SDC:
- receives updated rates of tax and other levies
- calculates tax and levies on the sale, and composes an invoice
- sends encrypted sales data to the TA
- receives an ‘audit’ confirmation from the TA
- provides data to the POS to print a fiscal invoice
