I agree that security could and should be a huge concern. With your credit card you're protected from fraudulent transactions. But this is not the case with ATM. If someone gets a hold of your ATM + PIN, you're just plain out of luck. Not sure how that translates to this service, but if something is compromised, you might just end up with an empty bank account.
