(Memphis) Thousands of Apple lovers now have their hands on the new iPhone.
One of the new features is called Touch ID, a fingerprint identity sensor.
However, some folks wondered if the fingerprint scanner is really the right type of protection.
For example, is it safe from hackers? Will your fingerprints some how be stored in a government database?
Experts say the technology is here to stay.
According to Apple, the touch ID sensor reads a fingerprint and unlocks the phone.
It can even be used it to authorize purchases through stores.
On the other hand, is fingerprinting safe from hackers and the growing risk of identity theft?
Hollywood movies make lifting prints look easy. Security researcher Marc Rogers warns that it depends on how the software giant implements the technology.
"Apple has clearly thought about this because the data is not going to be stored in the cloud so there's not going to be a giant database of lots of people's sensitive information that would be a prized target of hackers or enemy state hackers," explains Rogers.
He says fingerprinting is convenient for users and will be a boost to the mobile industry. "It could open a really huge universe of opportunities."
