Loading with EC card

Hello, I drive a plug-in and usually load at home. I often loaded in a supermarket. Free. Now they want money. There are 3 options available for this. With app with charging card with credt card Apart from the fact that I have never used the chip on the EC card, I don’t even know where to load it. I looked at the vending machine today and found none of it in the menu. I seem to be too stupid for it. The QR code reader of the app also doesn’t respond to the QR C odes. Displays unreadable. Now the option with credit card. If I scan the codes, I will see the page where I have to enter my data and agree to everything. Then 50 euros will be deducted. So far I know that. When I did this before it turned out that the charging station was broken and did not supply electricity. Now I didn’t want to go any further because I read the code from the photo. What’s next? Do I need my IBAN or what? Where I experience the failure h atte did this via Paypal. Luckily I drive a plug-in and am not dependent on the circus but there I would like to load because it is worth it time for me. Thanks to the loading professionals
