Re: Two factor of sorts can work here
I don't do company on-line banking but I presume there must be some emulation of the way cheque signatures have traditionally been done.
Cheque up to £x? One signature.
Cheque over £x? Two signatures.
In an on-line system the first person logs in and sets up the transaction. The second person authorises it. And in my view it has to be in that order - no emulation of pre-signing blank cheques allowed. If this facility is available then one thing is certain, judging by the scams, not enough companies are making use of it.
