How secure are the transactions on my Obopay Prepaid MasterCard?
The transactions you make with your Obopay Prepaid MasterCard will require the entry of the PIN you select for your card transactions. You should not write this PIN on your card, or keep the number with the card. You should not share this PIN with anyone. An Obopay employee will never ask you for this PIN. You will be able to change your PIN online at any time.
