The iPhone 5s will feature an NFC chip and another NFC chip which can be implanted under the skin in your hand to unlock the device, thus increasing security.
The sub-epidermis NFC chip is 60% smaller than a grain of rice and is intended to stay there indefinitely as it will require no upgrading because it's only used to transmit a 256bit AES public key with their phone, and any future phones.
Apple's Tim Cook believes with ever increasing amounts of private information held on a phone the existing security measures are inadequate.
They trailed Iris, and finger print scanning but found it to be too slow and unreliable in many situations, like dark environments or where the users hands were covered.
iOS6 supports NFC to unlock the device and Passbook also includes support for NFC, but the hardware wasn't included in the iPhone 5 as the payment gateway wasn't ready, nor the regulatory approvals for the epidermis chip applicator.
Apple is expected to introduce the iPhone 5S in the fall of 2013 with support for American Express ExpressPay, Mastercard PayPass and Visa PayWave.
-------------------------------
I guess they're getting the info out sooner than usual cos of the novel under skin chip.
I think that's pretty cool, no more passwords/pins, just pick the phone and it knows who I am.
Would also make payments much more secure.
I bet Android will do this too as most new handsets already have NFC readers, and at least Apple is using the open NFC standard.
