You can pay with your phone

Get ready to leave your wallet at home and pay for everything with your iPhone 6.That's the vision Apple set forth with Apple Pay, a wireless, digital wallet that is coming out in October. To pay for stuff at a store, just put your finger on the iPhone's fingerprint sensor and hold it up to the register. Beep. You're done.
Want to pay for something in an app? Just tap
"Pay with Apple Pay," put your finger on the fingerprint reader, and you're done.
The charge goes straight to your credit or debit card or whatever you've set up with Apple.
Apple Pay works by sending payment information via short-range radio waves. The message goes from a special chip inside the iPhone 6 to the register. It's called NFC(Near Field Communication). This feature is already on some Android, Windows Phone and BlackBerry devices and works with Google Wallet, Softcard, PayPal and other services. An estimated 220,000 retail stores already have NFC devices at the register. Apple Pay will be easier, safer, and available with every major credit card.
Why it's easier: The fingerprint scanner. A simple touch is quicker than typing in your PIN for a debit card, or signing a receipt for your credit card.
That feature could backfire, though. Apple's TouchID system is known to reject an iPhone owner's stored fingerprint. If it proves to be buggy or slow, expect users to skip the option altogether.
Samsung's Galaxy S5 smartphones let you pay by fingerprint too (using eBay's PayPal). But it requires an annoying extra first step: using the app to "check into" a store.
Why it's safer: Again, your fingerprint. No one else has it, so others can't fake being you (unless they cut your fingers off-watch out for that).
By comparison, if someone steals an Android phone and knows your four-digit Google Wallet PIN, they could use your wallet until you remotely disable the phone.
Mobile payments also make you less vulnerable while shopping. It cuts retailers out of the credit card information loop.
Apple Pay and other mobile payments systems never give shops your credit card information, because your smartphone never keeps it in the first place.
To add your card to Apple Pay, you snap a photo of it. The picture goes to your bank, which sends your phone a special key. That key is what gets stored on your phone (in a locked, protected zone).
At checkout, the key generates a one-time-use, unique code -- not your credit card information. The bank verifies the code. Apple and other mobile wallet companies never get any information about your transactions. It's more privacy all around.
Even if hackers steal the codes, they're useless. They won't work twice. It's a major improvement over the static, easy-to-copy information on your current credit card.
Where it's available: Apple Pay will work with American Express, MasterCard and Visa.
