# MIA QR Types

Within the QR MIA API, QR codes can be generated in several formats, depending on the usage context and the required level of transaction detail.

* **Static QR** – A predefined QR code with fixed data (no amount or personalized details). It is suitable for recurring payments where the amount is manually entered by the customer (e.g., donations, flexible contributions).
* **Dynamic QR** – A one-time generated code that includes specific transaction details such as the amount, merchant ID, and optionally customer information. It is ideal for cases where accurate and secure payment tracking is required.
* **Hybrid QR** – Combines features of both static and dynamic codes. It may be used for both one-time and recurring payments, where some data remains constant and other data is transaction-specific.

The choice of QR code type should be based on the operational purpose and expected user behavior.
