Almost similar to PayPal. You link your card and verify it. It takes couple of days I guess and make merchant payments using it via Skrill. Also you can load e-wallet with money via bank transfer or credit/debit cards and make payments using it. If I'm not wrong, they take some charge for loading.

Is it confirmed officially somewhere? When I search I get various results. One of which is below and says 23rd onwards. Nevertheless, pretty much excited this time.
Saw it somewhere at steamgifts or reddit, can't recall. Generally they starts on Thursday (so 26th seems correct) and ends on Monday as per our time.
