Steam wallet money to PoE points?

Can money from the steam wallet be transferred to this game to pay for points?

Yes. Just play the game through Steam and add points through the Microtransactions Tab (ADD POINTS by your current balance).

It's my preferred method. Nowadays everyone is getting hacked for credit card information and I like to keep my transactions in as few places as possible, not that I think Steam is more secure than anywhere else...
