# What is the registration procedure (KYC)?

KYC, or **"Know Your Customer"**, is a **regulatory compliance measure** used by businesses and financial institutions to **verify the identity of their customers**
****
This process involves collecting **personal and financial data**, such as:

* **Identity documents**,
* **Proof of address**,
* **Information about economic activity**,

The goal is to **prevent fraud, money laundering, and other illicit activities**.

## Mandatory Process

Following the publication of **Decree No. 2021-387**, **PSANs (Digital Asset Service Providers), including StackinSat, are required to verify customer identity from the first euro deposited**.

📌 **Without a validated KYC, StackinSat cannot convert your euros into Satoshis**.

📌 **When creating your StackinSat account, you agree not to make a bank transfer before your KYC is validated**.

These procedures are implemented **to comply with regulations** and **prevent risks related to fraud, money laundering, and terrorist financing**.

To complete KYC, you will need to follow a **quick and simple identification process**, which includes filling out a **form** and submitting the **necessary supporting documents**.
