Apple launched iOS 11.2 with Apple Pay Cash

Apple releases iOS 11.2 which is the second major update to the iOS 11 Operating System. iOS 11.2 is available in all eligible devices. To update, go to Settings --> General --> Software Update. Eligible devices include the iPhone 5s and later, the iPad mini 2 and later, the iPad Air and later, and the 6th-generation iPod touch. 

It brings several new features and important bug fixed.They introduced Apple Pay which makes transfer of cash from person to person easier. Cash is sent from a linked debit or credit card, while received cash is stored in an Apple Pay Cash card in the Wallet app and can be used for purchases or transferred to a bank account. 
For the iPhone X, iPhone 8, and iPhone 8 Plus iOS 11.2 appears to introduce faster 7.5 W wireless charging speeds through compatible Qi-based wireless charging accessories. At 7.5 W charging speeds, the three new iPhones are able to charge faster wirelessly than with the standard 5 W wired iPhone power adapter. When it comes to the iPhone X interface, iOS 11.2 adds a small bar underneath the status bar icons located at the upper right side of the Lock screen, which is designed to make the location of the Control Center gesture more clear. On the iPhone X, Control Center is accessed by swiping down from the top of the device.
