Help the Aged has set up a meeting with Apacs, the UK payments association, to discuss running a campaign in response to concerns about chip and pin cards.
The charity wants to highlight alternative payment methods to older people and those with a cognitive impairment who struggle to use chip and pin. An unpublished study by University College London researchers found more people than had been assumed are struggling to remember their pin numbers or to use the keypad.
The meeting was called after six charities countersigned a letter printed in The Daily Telegraph last week, which alleged that Apacs was reluctant to publicise chip and signature cards.
"At the very least we want Apacs to re-publicise the existence of chip and signature cards to the most affected groups," said a spokesman at Help the Aged.
