### What is an EPC QR Code?

The EPC QR code (European Payments Council Quick Response Code) is a standard for encoding SEPA credit transfer data. In Germany, it's known as "GiroCode". When scanned with a compatible banking app, it automatically fills in all payment details, reducing errors and making donations effortless.

Supported in 36 SEPA countries including: Germany, Austria, Belgium, Netherlands, France, Spain, Italy, and more.

### Use Cases

- Non-profit organizations accepting donations
- Churches and religious organizations
- Sports clubs and associations
- Crowdfunding campaigns
- Event organizers collecting fees
- Any organization accepting SEPA bank transfers

## Installation

5. Configure your bank details in the block sidebar

### Requirements

## FAQ

### Which banking apps support EPC QR codes?

Most European banking apps support EPC/GiroCode scanning, including:

- Sparkasse
- Volksbank
- Deutsche Bank
- ING
- N26
- Revolut
- And many more...

### Is my bank data sent to external servers?

No. All QR codes are generated locally - in your browser (editor) and on your server (frontend). Your bank details never leave your infrastructure.

### Can I customize the appearance?

Yes. You can change the background color via the block settings. For further customization, you can add custom CSS targeting the `.donation-qr-block` class.

### Does it work without JavaScript?

Yes. The QR code is rendered server-side as a static image, so it works even if visitors have JavaScript disabled.

### What if the QR code doesn't appear on the frontend?

The QR code requires the `endroid/qr-code` PHP library. Install it via Composer:

```bash
composer require endroid/qr-code
```

Without this library, the block displays bank details only. The editor preview always works regardless.

### Can I set a default donation amount?

Yes. You can set a default amount in EUR via the block settings. The default is 5 EUR. Set it to 0 if you want donors to choose their own amount.
