With the release of iOS 7 and OS X Mavericks in 2013, Apple improved their iCloud service by adding in iCloud Keychain. This allowed users to sync sensitive data securely between their Apple devices. Included among this were login credentials for websites, wifi passwords, and even stored credit card information, which could then be automatically entered into a form on a website.
To add in new credit cards, Apple already allowed users to manually add information in their Safari settings. Now, with iOS 8, it looks like Apple is taking this a step further by adding in support for scanning credit cards and automatically adding in that card information.
Using a form of optical character recognition, or OCR, an iOS device can scan a credit card and automatically fill in the data that it recognizes on the card. That card is then available for use online, and it is stored as securely as other important information in iCloud Keychain.
While this is great for people that buy things online, it also could be useful down the road, should Apple set up a mobile payment platform. With users entering credit card data into their Apple accounts and becoming familiar with Touch ID for security, it could open the way for iOS users to easily pay merchants from their iOS devices.
