Can you imagine when you have macular degeneration, limited motor skills, trying to use a mobile phone to make a payment?
And anyway, electornic funds transfer is a con. Cheques are far safer. If you do an online transfer, do you believe the banks check who you're paying is who you want to pay? No, they don't. The name is 'for your reference'. They are ony concerned about limiting their liabilities and costs, not providing a robust secure system for customers.
One digit error in the account number or sort code, and you could end up paying Vistoria Bischoff rather than your favourite relative.
So I now would rather use a cheque - I'm scared of making a mistake or being provided with the wrong numbers.
