About SoftSDC

SoftSDC is an application designed for Point of Sale (POS) mobile/desktop devices that converts non-fiscal invoices into fiscal ones.

How It Works

The application works in compliance with technical specification for E-SDC under the fiscal system powered by TaxCore V3. Installing SoftSDC on your device transforms it into an ESDC (Electronic Sales Data Controller). This allows your device to connect your POS application with the Tax Administration's security element and generate properly reported fiscal receipts.

To use the application, you'll need a smart card reader installed on your device. This reader can either be integrated into the device or connected externally.

Key Features

SoftSDC operates as a standalone service dedicated to a single POS device exclusively. This POS can be connected either to the same device (phone, tablet, or computer) or to a different one. Communication with SoftSDC happens through an API, where JSON messages are exchanged via HTTP protocol. SoftSDC also processes all commands received from the TaxCore.API in accordance with E-SDC technical requirements.
