I am not sure what Paypass is, but anonymous credit cards generally fall into two categories. The first category consists of likely-illegal underground cards that are generally very expensive to obtain (talking in the area of $500-$1,000 just to get the card) and which are loaded with things like Pecunix or Bitcoin. The second category consists of cards that you can buy at a convenience store without showing ID, and which are funded with cash at a convenience store, or by buying reload packs with cash at convenience stores. In the case of the underground cards, the policies and procedures will vary and you are best to ask the person who sold you the card, or to look at their website. In the case of the cards sold at convenience stores, they are actually not nearly as anonymous as they seem to be. These cards fall into two categories, reloadable cards and non-reloadable fixed value cards. For any card that is reloadable, and any card that has more than $500 on it, you need to tie the card to your social security number to actually use it for anything. You can purchase the card and put funds on it without tying it to your identity, but to actually activate the card you need to call a number and give identifying information such as your social security number, as well as undergo a background check. After your identity is confirmed, the card is then activated and the PIN is then mailed to you via snail mail. The only legal anonymous cards are non-reloadable prepaid cards with under $501 dollars on them, but these cards have many restrictions put on them. If you want to buy something off of the internet you will need to tie a social security number to the card, they can only be used anonymously for in person purchases. Additionally, these cards can never be used for cashing out at an ATM. It looks like Paypass is an official Mastercard reloadable card, and not something being offered by underground criminal networks in Russia.Therefor, chances are extremely high that you get your PIN by calling them, giving up your social security number, having a background check run on you and then having the PIN mailed to your address. Unfortunately you are likely going to have to do this now if you want to get access to the funds on your card, since at this point they are essentially frozen until you confirm your identity. It is unfortunate that so many people seem to think these cards are actually anonymous, it is definitely the impression somebody new to them would have though, as you can purchase them and load money to them at a store without ever having to show an ID. You need to read the fine print to realize that the card you buy at the store is just a marketing gimmick for the most part, as you need to call a number and have your identity confirmed prior to using the card, and you generally will be sent a new card in the mail with your PIN on it after you actually verify your identity and get your account activated. There are indeed real anonymous prepaid cards, but as I already said they are very often illegal (possibly not to own but I am not sure on that, almost definitely to sell though, and they are shut down and pop up again on a fairly frequent basis). These services tend to charge a large amount of money to obtain a card which can then be funded directly via Bitcoin or Pecunix (or E-gold or Liberty Reserve in the past). The card issuer acts as an exchanger, charging perhaps a 1% fee to load the card after receiving the Bitcoin or Pecunix to put on it. These cards are very frequently sold from countries such as Russia, and you tend to need to do a lot of digging to find a provider of this sort of card, and you need to do your homework to make sure the provider is legitimate and not a scammer. Also, these providers tend to be identified and have the banks backing them pull out after only a few months to a year or so of operation. They are still useful though, as you can have them shipped to a fake ID private mail box and use them for anonymously cashing out E-currency at ATM's. I know two vendors who have cards like this, one of them has about a dozen different ones and he can cash out something like $12,000 worth of Bitcoin a day at ATM's without ever having had to give the provider of the card any of his real information.
