Apple has recently launched Apple Pay, a new one-touch payment system using only your iPhone.

People can now pay for things without physically using a credit/debit card; the information is all stored into your phone. Using the Passbook app already in the phone, users can store their credit card data for future purchases. To pay for a purchase, the user must hold down the TouchID fingerprint sensor on the phone and point it at the Apple Pay reader. Using near-field communication (NFC), a short-range wireless connection, the reader connects with the phone, and the item(s) are paid for.

It is available for the latest Apple phones: iPhone 6 and iPhone 6 Plus. To use Apple Pay, the phone needs to be updated to iOS 8.1 operating system.

Apple Pay works with credit cards Visa, MasterCard and American Express, as well as debit cards from major banks including Wells Fargo, Citi, Chase, Capital One and Bank of America. It is also accepted at more than 220,000 retailers across the country including McDonald’s, Walgreens, Whole Foods and Macy’s.

Some have wondered what happens if your phone is lost or stolen? Apple suggests using its 'Find My iPhone' app from a computer and put the phone into ‘lost’ mode and suspend the usage of Apple Pay.

Really excited for ApplePay. Not excited about the day when my wallet runs out of batteries.

Now, some believe that Apple has created something brand new. However, Google has had their own version since 2011, Google Wallet. So why aren’t people talking about this? Critics note Google’s lack of marketing on the product.

just used apple pay for 1st time. not a game changer if you're one of the 3 people (like me) who are used to google wallet on a nexus phone
