Amazon app store for iOs now enables users to access their online accounts with the help of the Touch ID fingerprint sensor from I Phone, as reported in Geekwire.

These new features were developed taking into consideration the new iOs system usability released.

One thing that will leave users baffling over the operations of the Amazon app store for iOs is its on/off features. Many users don't have a single idea on how to turn on/off the device. Manual indicating helpful information for this operation is not available, either.

An Amazon app store for iOs representative did not provide comments to help users navigate the operational functions, according to a report from Geekwire.

The mystery behind the operational systems of the device is one of the firsts for a security-angled app.

Setting the on/off mode at default will put the users' mobile devices at risk of getting hacked. Hackers are able to prey on the I Phones behind the users' back if these features are not set at default. People with bad intentions easily replicate fingerprints without a problem.

Critics argue, however, that the marketability of Amazon will have done better if more feature and security options are available in one package. Amazon may need to reconsider the advancement of their device's features to attract consumers with multiple preferences. Targeting a wide consumer demographic is the key to Amazon's sales increase and market popularity.
