A US lawmaker questioned the fingerprint recognition in Apple's iPhone 5S. Senator Al Franken wrote to Apple head honcho Tim Cook to air his concerns over what he calls "substantial privacy questions" that come with the new technology. He gave the company a month to answer the questions he had written in his letter.

Meanwhile, a contest has been promoted on website istouchidhackedyet.com that challenge all hackers to crack the code of the iPhone 5S fingerprint scanner. The first hacker to break the code would win more than USD 13,000 in cash and other goodies like booze, Bitcoin currency ad books.

IO Capital, a micro venture capital company based in Chicago, gave USD 10,000 to be part of the contest prize. IO Capital Founding Partner Arturas Rosenbacher said the contest would help Apple find bugs in the program that may have been overlooked. He told Reuters, "This is to fix a problem before it becomes a problem. This will make things safer."
