A number of charities and support groups have raised concerns over the issue of chip and pin for elderly and disabled people.
As today marks the deadline for people to stop signing their receipts and start using their pin code, there are concerns over the number of vulnerable members of the community who will struggle with the new system.
Elderly and disabled people will be at a disadvantage, warned the Royal National Institute for the Blind, as they may have problems remembering the code or using the keypad.
Help the Aged also believes that the system will not be beneficial to older people, with bad eyesight, arthritis and memory problems preventing them from carrying out the transaction and adding stress to a simple shopping trip.
"There are large numbers of people in the country who will struggle to use chip and pin cards. These include individuals with low-level dementia or other memory impairments but also older people who are just not used to being compelled to remember a PIN number," explained Paul Bates from the charity.
"The banking code needs to be changed so that banks are forced to offer better information on chip and signature cards instead of pushing chip and pin."
