Maybe this is what they are talking about...........
to confirm a debit card , first there is a charge of 1.50 deducted from your bank account. A 4 digit number will then appear on your bank statement . You must use this 4 digit number to confirm your bank a/c .
I had to do this to confirm my credit card , but i cant remember whether i had to do same with my current a/c .
Paypal is a secure way to send and receive money , but I find their commission a little bit on the high side
