Chip making giant Qualcomm (QCOM) - Get Report on Wednesday unveiled a new fingerprint sensor that the company says brings a new form of security.

Qualcomm showed off the under-screen fingerprint sensing technology at Mobile World Congress 2017 in Shanghai. Chinese phone maker Vivo is the first to use the technology in a phone. Vivo released a video showing off the fingerprint tech as a concept.

"The new suite of features, compared to the previous generation, supports more design flexibility for operators and original equipment manufacturers (OEM) by making it easier to differentiate products with unique form factors and advanced features and designs. Qualcomm Fingerprint Sensors for Glass and Metal are expected to be available to OEMs this month, and are expected to arrive in commercial devices in the first half of 2018," Qualcomm said.

What's Hot On TheStreet

The stock market may be overvalued: Now may be the time to pay extra attention to red-hot tech stocks such as Apple (AAPL) - Get Report and Facebook (FB) - Get Report . As TheStreet first reported Tuesday afternoon, asset valuations are somewhat "rich" by standard metrics, Federal Reserve Chair Janet Yellen said in London during a conversation about economic issues with British Academy President Lord Nicholas Stern. Yellen's comments on equity valuation and bank strength closely mirrored Fed Vice Chairman Stanley Fischer's from an IMF event held earlier in the day.

The iPhone has changed how you make money: TheStreet's Scott Gamm is out with a piece that will really get you thinking. Apple's iPhone will turn 10 years old on Thursday. The device not only turned Apple into one of the world's most valuable companies, helping to boost its stock price more than 700%, it also changed the way we invest and trade stocks Gamm points out.

In fact, the original iPhone -- and the current versions -- have an internal stocks app, allowing users to check the broader market indexes and individual stock prices. Having this in your pocket was a big deal 10 years ago.

"I think it's actually made the life for a typical investor much easier," Angelo Zino, an analyst with CFRA Research, told TheStreet. "I think they've been able to tap news flows much quicker."
