When Apple announced that the Apple Watch would be able to use Apple Pay, the company's new mobile payment initiative, many wondered how secure the payments would be if the device lacked the security of Touch ID, which is used in the iPhone 6's implementation. Now, several members of the press have confirmed how the system works.
MasterCard's mobile payment executive Ed McLaughlin also told Re/code that the Watch would use the four sensors on the back of the device as a security measure, while Visa CEO Charlie Scharf said that Apple understood the risks of contactless payments and has a solution.Thanks to sensors on the Apple Watch's back, the device can tell when it's being worn and when it has been taken off. When you first put the watch on, you must enter a code. When the watch is removed from your wrist, the watch locks itself and can't be used for payments unless the code is entered again.
The Apple Watch is due to arrive in early 2015 and will start at $350.
