If you are going to go to the trouble of getting a netteller card with a static number, you might as well ask your bank for a card. I have a Mastercard from ABN-AMRO which has no 'credit' - the whole balance is deducted from my current account each month. A nice alternative if you want to shop on the web but don't want a real credit card, with the possibility of racking up interest charges. The limit is set low, so if it is ever compromised, the amount of possible damage is limited.
