As rumors go, I'm betting the latest are on the mark. According to AppleInsider, The China Times has reported that the iPhone 5S, rumored to arrive this summer, will come with both a fingerprint sensor and near-field communication chip. According to the report, you'd be able to simply touch your phone to make a payment. The sensor would recognize your touch, and the NFC chip would communicate your authorization to an NFC mobile payment terminal at the point of sale.
