Apple's unveiling of iOS 8 at WWDC last week was accompanied by a number of surprises, but users are still discovering more features, like a new credit card scanning option in Safari
The feature allows you to use your iPhone's camera to detect your credit card number when prompted by a website during online transactions.
When a credit card field is presented in the iOS 8 version of Safari , you'll see a "Scan Credit Card" option, a new section for passwords, and the AutoFill option that was already available in iOS 7, which lets you save card details for future online purchases. The new feature uses character recognition to translate the image of your credit card into distinct numbers for your iOS device, according to 9to5Mac .
Another lesser-known feature of iOS 8 is that it generates random MAC addresses when scanning for Wi-Fi networks, a feature that will make it harder for advertising companies to track you via your MAC address.
Given the many changes in iOS 8, a few more surprises are likely to emerge in the coming weeks. But unless you're a developer or participated in Apple's public beta program, you'll have to wait until the fall to take advantage of all the features.
