Translations:Fundraising 2012/Translation/Donor information pages/3g/qqq
Due to different reasons (small error on the info, small amount, transaction pattern) some banks just 'flag' the donation/transaction as a 'need to confirm' because they think it may be fraud. The donor then, needs to call the bank and release the hold (and will probably need to place the transaction again). So possible alternatives to 'flag' for translation are 'suspend', 'mark', 'block'.
