The launch of the iPhone 5s has triggered a number of questions regarding the new fingerprint sensor, including the attention of an U.S. senator.

Apple's latest smartphone offering, the iPhone 5s, includes the introduction of the Touch ID security, and the Cupertino-based organization is making sure users understand the technology.

Apple launched a FAQ page where it noted much of one's digital life is stored within their iPhone and how everyone should use a passcode to protect such important information.

"Unfortunately, not everyone does; more than 50 percent of smartphone users don't use a passcode," Apple stated, adding fingerprints are one of the "best passcodes in the world."

Apple continued, "It's always with you, and no two are exactly alike. Touch ID is a seamless way to use your fingerprint as a passcode. With just a touch of the Home button of your iPhone 5s, the Touch ID sensor quickly reads your fingerprint and automatically unlocks your phone. You can even use it to authorize purchases from the iTunes Store, App Store, and iBooks Store."

The technology for the Touch ID, however, has brought concern from U.S. Sen. Al Franken, who serves as chairman of the Senate Judiciary Subcommittee on Privacy, Technology and the Law.

In an open letter to Apple CEO Tim Cook, Franken called on the Cupertino executive to answer a series of questions. Franken, who admits to being an iPhone owner, noted the Touch ID might improve mobile security, but said it further raises privacy concerns.

Sen. Franken listed 12 questions for Cook, ranging from the possibilities third parties might have for the fingerprint data, extracting and obtaining fingerprint data from an iPhone, and ensuring Apple will never share fingerprint data with other parties.

Franken posted the open lettter on Sept. 19 and requested Cook to issue a response by the next month.

The iPhone 5s, with Touch ID, launched in the U.S. on Sept. 20 featuring the latest mobile operating system by Apple, iOS 7.
