As biometric technology becomes ever more common, bank customers will soon need more than their PIN number and an ID to get their cash.

As the Credit Union Times reports, Goode Intelligence, a London-based security consulting company, says that by the year’s end around 450 million bank customers worldwide will be using some form of biometrics to do their banking.

According to Alan Goode, founder of Goode Intelligence, "There is a growing desire from the banking industry to adopt convenient methods to verify the identity of their customers and this is creating the conditions to drive the adoption of biometrics in banking even higher.”

Explaining the security changes to come, Goode says that, "Banking adoption of biometrics is creating a booming biometrics industry with biometric vendors experiencing tremendous growth on the back of the escalation of consumer-led adoption of biometric authentication.”

"This is not just about Apple’s Touch ID and fingerprint biometrics,” he empasizes. Biometric technology will soon be making much use of hand geometry as well as facial and voice recognition.

As of now fingerprint verification has some flaws. According to a German hacker named Jan Krissler, a properly motivated individual can easily bypass the touch-related finger scanners.

Krissler, who goes by the name "Starbug," hacked Apple's Touch ID one day after it was launch by simply replicating the last fingerprints that had touched the glass iPhone surface. To pull off the big scheme he used a printer and some glue.

The BBC reports that the hacker says that any decent protection requires what he calls a "two-factor authentication.” This twofold test is based on independent components from one of three methods: knowledge, possession, and biometric technology. Summing up the problem with this system, he says, "if you are able to make a dummy finger from fingerprints found on the phone, the two factors are only worth one.”

According to the Guardian Krissler said, “I consider my password safer than my fingerprint… My password is in my head, and if I’m careful when typing, I remain the only one who knows it.”
