苹果发布两款新iPhone

 

The 5S introduces a fingerprint sensor built into the phone's main button to identify the user. The 5C comes with a plastic back in a choice of colours.

 

It marks a change of strategy for Apple which had not launched two distinct types of handset at the same time before.

 

The iPhone is the firm's most important product in terms of earnings⁵ power.

 

The new fingerprint system can be used to unlock the 5S and provide authentication⁶ for purchases from Apple's online marketplace.

 

One analyst⁷ suggested the feature would help the handset stand out against its Android rivals.

 

"Touch ID is actually quite an elegant solution to an ever more significant problem: namely, the theft of mobile devices and, perhaps even more critically, the information stored on those devices," said Windsor Holden from the tech consultancy Juniper Research.

 

"Many people haven't yet bothered to implement⁸ any kind of security solution on their handsets and for those who have, securing handsets with Pin authorisations can be quite a time-consuming process."

 

However, Apple is not the first phone company to offer such a fingerprint reader.

 

Motorola added the facility to its Atrix handset in 2011, but many owners had problems using it. The feature is not included in the Google-owned business' latest models.

 

The new handsets are compatible with the radio frequencies used by O2 and Vodafone's new 4G services in the UK. The only 4G network the old iPhone 5 could use was EE's.
