# Generate a QR code for in-person payment
qr = client.create_qr(amount=1500.0)
print(qr.qr_token)            # base64 QR image token
print(qr.qr_operation_id)     # poll status with this

# Poll QR status
status = client.qr_status(qr.qr_operation_id)
print(status.status)          # "WaitingForPayment" | "Paid" | "Expired"

# Refund
client.create_refund(qr_operation_id=12345678, return_amount=1500.0)
