Financies? never on a mobile device.
I recently had a conversation a gentleman at $BANK who told me that their mobile banking app was more secure than online banking with a desktop PC. When I suggested that he was a jester with a fine sense of irony he told me that transactions on the mobile app were subjected to more than twice as many secondary checks as those from PC-based banking.
From this I infer that $BANK are more than twice as worried about dodgy transactions from mobile as from other online banking.
