This is a prepaid debit card, every card comes with a 4 digit pin & it is safe to use everywhere in the world that accepts master card & visa & american express. I have enough supplies to make 20+ Master/Visa Credit/Debit cards per day. The card won't ever get frozen and can be used just like a regular debit card, These cards can be used to shop in stores and you can use them to cashout in ATMs worldwide.
