PerkStreet Financial is offering a $25 “signing bonus” to consumers who start an account with the online financial services provider by Christmas Day.

The deal, which went into effect on Dec. 15, requires that the new account be funded by Dec. 25, as well as that the new customer use his debit card to “make 3 purchases within 30 days of opening your account.”

The offer is in addition to the 2% cash back PerkStreet pays on every non-PIN purchase with a PerkStreet debit MasterCard.

Dan O’Malley, founder and CEO of PerkStreet Financial, will be among the speakers at the upcoming Bank Innovation 2012.
