Yes, First Direct do that too.
Harry, paying in at the PO was a new experience for me.
I asked the lady if I could pay in money to my FD account. She said stick your card into the machine and I'll tell you what you can do.
Once I had done this, she gave me a choice of services, so I guess it depends who you bank with as to what services you have access to.
Anyhow, I handed over the dosh, she entered it on her keyboard and then the card machine lit up saying I wanted to deposit £XXX, press here if that is correct.
Once I had done that, I got a printed receipt and Bob was my Uncle.
