The new system is an expansion of the existing WoW Token, which allows WoW players to use gold to buy tokens to redeem for game time, or buy tokens with real money to convert into in-game gold.

is expanding that effort by letting players indirectly trade WoW gold for in-game items. On Battle.net
the gold that they’ve earned in World of Warcraft into credit can be
converted by players. The move allows players to convert their in-game currency
into virtual goods for other Blizzard products,
