The WoW Time Card Prepaid is a product that allows you to apply a subscription to your account in the game created by Blizzard for about two months. It can be said that it is a kind of relic of old times when people did not use credit cards and PayPal, which are currently very popular.
Time Card and an ordinary subscription are virtually the same. The difference between them is just that the Time Card is just cheaper and safer, which can make it more attractive to some players. You should also know that the above-mentioned WoW subscription is activated on the battle.net website.
