Everaja,
Our cards are virtual Visa cards used for online purchases only. We delivery them instantly after purchase as number, expiration date and cvv2 (and you can use any name and any billing address during purchase).
By the way, cards are reloadable, but currently such feature can't be used in automatic mode. But if anybody needs to add funds to already purchased card, it can be done manually after contacting us.
Also we can make a card with custom amount, but it also requires manual operations and possible after contacting us.
