Companies no longer sell physical time cards because the rate of theft you have to get a digital code from the registar, what you can also do is set up a debit card solely for the game and use it to buy crysta. You can also use 1 time prepaid cards as well. And from what I found is using a debit/credit card is pretty safe It only asks for ur numbers, sec code and exp date. No name needed and which iws needed to steal the card.
