> Nobody uses cheques, obviously (although they do exist).

Cheques are now mainly used for business to consumer payments, and for large value transactions, where it's done as a bank-drawn cheque usually.

The bank I use doesn't have a branch anywhere near where I live, so when I got sent a cheque a while ago I had to ask how to go about depositing it. Turns out the bank I use for my credit card will happily accept them via their ATMs which print out a receipt with a scan of the cheque.
