Natwest provides mobile bank help as branches close
Twenty eight communities across Wales have lost their last bank in the past two years, figures show.
Age Cymru said it was having a serious impact on the lives of elderly people living in the areas.
In March, the British Bankers Association, which represents the UK banking sector, pledged to try to minimise the effect of branch closures.
Natwest said one of the ways it is doing this is to have a 'Bank on Wheels', which travels to towns and villages to provide banking services.
One of the places it goes to is St Clears in Carmarthenshire, where people said it saved them travelling further afield.
