The HSBC App lets me pay a cheque in by taking a picture of it and uploading the picture - Max £500 one cheque, £750 in cheques in one day.
I believe Barclays has something similar but not used it.
That's very smart. Regrettably it seems that's not a facility yet offered by my own bank so I shall have to make a detour to the local branch the next time I am on my weekly shopping excursion.
