BALDWIN: If you're like plea, you have enough security passwords to fill a small diary, so replacing passwords with a thumbprint sounds like a dream come true, but is it really more secure and who can get access to the print? Can the government? Big questions we're asking here. First of all, finance correspondent, Zain Asher, is here to help us answer some of these. First things first, how does this even work with the phone?</s>ZAIN ASHER, CNN FINANCE CORRESPONDENT: Hi, Brooke. Well, basically there's a button on the iPhone 5S that doubled as a fingerprint scanner. Here's what's interesting, there are actually different levels of fingerprint security depending on how many different points on your thumb are actually going to be read. For example, some types of technology might use 16 different points on your thumb to verify it's you. The iPhone 5S however is probably going to use less because it may have to account for variables like if you burn yourself, for example. Obviously Apple, they don't want people to constantly complain they can't get into their phone. Now the problem is the fewer amount of points, the more likely it is for someone else around the world to have a fingerprint to access your phone. There's no chance you'll ever meet them or they'll ever get into your phone.</s>BALDWIN: Like the NSA, for example, Zain?</s>ASHER: Well, yes, there are some concerns about how vulnerable these phones are going to be to hacking. Here's what you have to understand. First, the thumbprint is going to be encrypted. Second of all, they're going to be stored locally on the actual phone on a chip. It's not going to be stored in some server or on the Cloud. You probably won't have to worry about that.</s>BALDWIN: Zain Asher, thank you. Back after this.
