# What is Fraud detection?

**Fraud detection** is an optional premium module in **Fitek** designed to help You reduce payment fraud risk by **automatically verifying the bank account on an invoice** against the bank accounts saved on the supplier card.

It adds an extra security layer right where payment details are reviewed: the invoice **“Pay to account”** field.

### **How it works** <a href="#how-it-works-bank-account-verification" id="how-it-works-bank-account-verification"></a>

Fitek compares:

* the bank account in the invoice **“Pay to account”** field\
  **vs**
* the bank accounts saved on the **supplier card**&#x20;

#### **What You see** <a href="#what-you-see" id="what-you-see"></a>

Next to **“Pay to account”**, Fitek shows one of two results:

**Verified icon**\
Shown when the invoice bank account **matches** any bank account on the supplier card (Main or Other).\ <br>

**Warning icon**\
Shown when the invoice bank account **does not match** any bank account on the supplier card **or** when the supplier card has **no bank accounts saved**.

### **When the check happens**

The comparison runs automatically, so You don’t need to remember to do it manually:

* **Every time You open an invoice**
* **After any change** to the **“Pay to account”** field
* **After any supplier change** on the invoice

### **Your control remains complete**  <a href="#your-control-remains-complete-important-behaviour" id="your-control-remains-complete-important-behaviour"></a>

* The result is **visual only**: it **does not block** invoice processing.
* Invoices remain **editable and processable**; You keep control of Your workflow.

{% hint style="info" %}
Bank account comparison is performed while the invoice is in processing; on **approved invoices**, the system does not re-run the comparison, but the **latest icon remains visible**.
{% endhint %}
