When my dad wants money from his bank I have to take him to the supermarket cash point. He hands me the card then I put it in for him then he tells me the number which I put in for him. Then I hand him back the card and then I give him the money and he puts card and money into his wallet..
I always feel terrible when we do this but he cannot get the hang of the cash machine. He used to walk to the bank in town but he can't do that any more and it is not safe for him to go on his own anyway.
I don't know of any other way for him to get his money out.
Before Mum went into care (and before I became her POA) this is what we did. We never had to use a cashpoint but when we did her weekly shop, paid the hairdresser or bought new clothes she always handed me her card and said “just you do it please.” She always kept the card but would never use it as she found it too confusing.
