Software manufacturer Apple’s iPhone 5S, now speculated to have a fingerprint reader and along with it the company is also expected to release a cheaper and plastic version of the mobile phone.

Apple has released a new version of the iOS 7 beta software, which has a radically different design and some new features including new “siri voices” and a control center with easy access to settings menus and it also contains some clues about a fingerprint sensor in the device.

An iOS developer said that the new software contains a folder called ‘biometrickitUI’ in the code which mentions  a fingerprint that changes colour during the setup process and a source familiar with the new iPhone said that the fingerprint implementation has been complete.

Increased speculations about the a cheaper and plastic version of the iPhone indicate to the earlier reports about Apple working on cheaper phone that would be available in a variety of colors to appeal to the lower end of the phone market.
