Iris-scanning Samsung Galaxy S5 could launch in April

Samsung's eagerly anticipated Galaxy S5 smartphone may include an eye scanner for the first time, according to a recent interview with the executive vice president of the company's mobile business.

The exact launch date is still yet to be announced, though it is expected to come by April alongside an evolved version of the Galaxy Gear smartwatch.

"We've been announcing our first flagship model in the first half of each year, around March and April, and we are still targeting for release around that time," Lee told Bloomberg news.

"When we release our S5 device, you can also expect a Gear successor with more advanced functions, and the bulky design will also be improved."

The iris-scanning technology would provide the Korean firm with biometric technology to compete alongside Apple's Touch ID fingerprint scanner that launched with the iPhone 5s.

"Many people are fanatical about iris recognition technology," Lee said. "We are studying the possibility but can't really say whether we will have it or not on the S5."

In October it was predicted by Goode Intelligence, an analysis and consultancy organisation, that mobile biometrics could generate over £5 billion revenue by 2018. The firm's report suggested that 3.4 billion users will be using biometrics on their mobile devices within five years.

"Biometrics on mobile devices will flourish", said Alan Goode, the author of the study and founder of Goode Intelligence.

"Apple's decision to launch its latest flagship iPhone, the iPhone 5S with an embedded touch fingerprint sensor, was a pivotal moment for the biometrics industry and will accelerate the consumerisation of biometrics trend."
