Features

Everything You Need for Fiscal Compliance

MySDC handles the entire fiscal signing workflow so your POS software doesn't have to.

Digital Invoice Signing

Every sales invoice is cryptographically signed using your FRCS-issued smart card before printing. Tamper-proof and fully compliant.

Automatic TaxCore Submission

Audit packages are automatically submitted to the FRCS TaxCore central server every 30 minutes. Zero manual effort required.

Local HTTP API

Any POS software can integrate via a simple REST API on port 8180. Sign invoices and verify PIN with straightforward JSON requests.

Offline / USB Audit

No internet? No problem. Store audit packages locally and submit later via USB drive or SD card when connectivity is restored.

System Tray Dashboard

Real-time status via a color-coded tray icon. Green = ready, Yellow = attention, Red = action required. At-a-glance at all times.

Receipt Verification

Every signed receipt includes a QR code. Customers can verify authenticity on the FRCS portal — building trust and transparency.

How It Works

Three Simple Steps to Compliance

MySDC fits seamlessly into your existing workflow with minimal setup.

Install & Configure

Run the installer as Administrator. MySDC auto-registers as a Windows Service, opens port 8180, and adds a Firewall rule — fully automated.

Insert Card & Enter PIN

Select your FRCS smart card reader from the tray menu and enter your 4-digit PIN. The icon turns green — you're ready to sign invoices.

Sign & Submit

Your POS sends invoices to the local API. MySDC signs them instantly and automatically submits audit packages to TaxCore every 30 minutes.

Tray Icon Status Guide

Green — Ready

Signing invoices normally. No action required.

Yellow — Attention

PIN required, audit pending, or clock sync issue.

Red — Error

Offline, no reader, storage full, or card error.
