  18. 18.  Google Wallet uses “near field communication” to make secure payments. NFC is a set of standards for smartphones to establish radio communication with each other by touching them together or bringing them into close proximity. It requires pin and additional security. It stores encrypted user information on a computer chip called “the secure element”. Android device can be locked with PIN. It requires additional pin to activate antenna of NFCchip. 18
  19. 19.  Itmust touch or be in close proximity to a “MasterCard PayPass” reader. Once the transaction is completed, the antenna is turned off. Additional transactions require the PIN to be entered again. 19
  20. 20.  Includes storing of data regarding payment information, transaction details, payment attempts and other information. Much of the data is stored but may not be shared outside Google except under certain circumstances. The Privacy Policy also indicates that transaction details are not "currently" stored by Google, implying that users transaction details will be stored at some point. The storage of such personal information about users transactions is of significant financial value to a company that earns much of its revenue from data, but may be controversial to users aware of the policies.  20
  21. 21.  Can be used only in Sprint Nexus S4G. Google Wallet is still accessible outside of the application. Hackers could create a way to intercept data by eavesdropping on Google Analytics which monitors apps used on the Android OS. 21
