Initializing the SDC

Each time you start FiscoBridge SDC, you need to initialize it before it can process invoices. Initialization connects the application to your smart card and verifies your identity through PIN entry.

Before You Start

Make sure:

Your smart card reader is connected to a USB port
Your fiscal smart card is inserted in the reader
FiscoBridge SDC is installed and running

Step-by-Step Initialization

Step 1: Open the Application

Launch FiscoBridge SDC. The application opens on the Status tab. On the left side, you'll see the hardware status fields.

At this point, the status will show:

Selected Card Reader — your connected reader
Card Status — whether the smart card is detected
PIN Status — Not Verified
Initialization Status — Not Initialized

Status tab before initialization showing card detected but PIN not verified

Step 2: Verify Your PIN

Click the Verify PIN button. A dialog appears asking for your smart card PIN.

Enter the PIN that was provided with your fiscal smart card and click Verify.

Note: If you enter the wrong PIN multiple times, the smart card may lock. Contact your tax authority if your card becomes locked.

Step 3: Confirm Initialization

After successful PIN verification, the system reads the certificates and business information from your smart card. The Status tab updates to show:

PIN Status — Verified
Initialization Status — Initialized
All Secure Element Information fields on the right side populated (Business Name, TIN, UID, etc.)

Status tab after successful initialization showing all fields populated

The SDC is now ready to receive and process invoices from your POS system.

Troubleshooting

Card not detected?

Make sure the smart card is fully inserted in the reader
Try unplugging and reconnecting the USB card reader
Check that the card reader appears in your system's device list

PIN verification failed?

Double-check that you're entering the correct PIN
Be careful with the number of attempts — too many wrong entries will lock the card
If the card is locked, contact your tax authority for a PIN reset

Initialization fails after PIN is verified?

Check your internet connection — the SDC needs to communicate with TaxCore.API
Make sure outbound HTTPS (port 443) is not blocked by your firewall
Try restarting the application and initializing again
