+# EPC QR Code Generator
+
+Generate EPC/GiroCode QR codes that can be scanned with banking apps to initiate SEPA transfers.
+
+## Workflow
+
+1. Determine recipient name, IBAN, amount, and Verwendungszweck
+2. Look up IBAN from `memory/contacts.md` if recipient is a known contact
+3. Generate QR code via script
+4. Send QR image to Moritz via message tool (use `filePath` for the image)
+5. **Delete the QR image file immediately after sending** (security - contains payment data)
+
+## Script Usage
+
+```bash
+python3 skills/helios-qr-bank-transfer/generate_epc_qr.py \
+  --name "Max Mustermann" \
+  --iban "DE89370400440532013000" \
+  --amount 25.00 \
+  --reason "Abendessen" \
+  --output /tmp/epc_qr.png
+```
+
+Script prints the output path on success.
+
+## Important
+
+- Always confirm amount and recipient with Moritz before generating if ambiguous
+- IBAN spaces are stripped automatically
+- Amount must be in EUR, between 0.01 and 999999999.99
+- After sending the QR code image, **always delete it** with `rm`
+- Never store QR codes permanently - they contain sensitive payment information
