Banks take security very seriously, as you'd expect. But what's more secure than chip & PIN technology at a cash machine?
The idea of chip & PIN is that no-one can access someone's bank account unless they have their card and know their personal identification number. Even so, banks are looking to the future, and one area that's being looked at is biometric technology: identifying people by their fingerprints, voice or iris.
An article in bankingtech.com takes a look at this, pointing out that as well as increasing security, it could also reduce the amount of paperwork that people have to produce to prove their identity.
The 'biggest hunger for biometrics', apparently, can be found in places like South Africa, India and Latin America, where there's less 'legacy' technology than in places like the UK, which means it could be simpler to introduce a new technology.
The article gives India as an example: the country's rolling out an ID project that uses only biometric technology and gives each citizen a unique ID number. This will 'eventually become the single source of identity verification' - and people 'will be spared the hassle of repeatedly providing supporting identity documents each time they wish to access services such as obtaining a bank account, passport, driving licence and so on'.
A spokesperson for thinkbanking commented: "Whatever security measures we see in future, there are some tips that'll still apply, from not using cash machines in dimly lit areas to making sure you tell your bank about any unusual activity in your bank account."
