Two thirds of consumers in the UK have problems remembering multiple four digit personal identification numbers (PINs) according to research conducted by data communications firm TNS on behalf of Visa International.
According to the study, only 29 per cent of consumers said they easily remembered a range of different four digit PINs.
The research found that each of us has on average three personal identification numbers committed to memory for day to day use, such as withdrawing cash from ATMs, setting a burglar alarm or a security code on a mobile phone.
Visa's research comes as the trial of chip and PIN payments continues in Northampton. So far 600 retailers have switched to the new payments systems and over 181,500 chip cards have been issued by participating banks in the town.
While Visa tried to put a gloss the results, noting that only four per cent of consumers are not at ease with remembering and using a four-digit PIN, the everyday experience of users in trying to juggle multiple codes and PINs may yet point to problems at the check-out in the future.
